Hi guys,
First of all i`m completly noob on this so don`t be much hard with me
ok. i`m trying to develop a simple app just to run 4 simple command to install another app but for now the only thing that i can get to work was asking for su permissions...
can someone help me with this?
Thks a lot
HTML:
try {
runtime.exec("su -c busybox mount -o rw,remount /system");
runtime.exec("cp /sdcard/gscript/xrecovery.sh /data/local/tmp/xrecovery.sh");
runtime.exec("chmod 777 /data/local/tmp/xrecovery.sh");
runtime.exec("/data/local/tmp/xrecovery.sh");
runtime.exec("reboot");
}
catch (IOException e) {
e.printStackTrace();
do not think anyone has the knowledge to help me: .- (
My intention is to create a simple program that installs a file which is in sh sdcard,
"sdcard / gscript / xrecovery.sh"
until now could only be granted access to the root but do not know where and what command should I put to run that sh file...
is that no one can / want help?
thks

You should be able to execute a .sh file by using:
Code:
sh xrecovery.sh

Thks; )

Of course you need to specify the path (it cannot guess where your script is, unless you add it to your PATH). So I guess the following should work for you:
Code:
Runtime.getRuntime().exec("sh /sdcard/gscript/xrecovery.sh");
Unfortunely i cant make this work UK sure that im putting the command Sony the wrong place. I've allready try put Sony a different pplaces but never work: (

first you'll have to copy the file from the apk-assets folder to /data/data/your.pqackage.name/file/file.format, after that you can copy it as root to the system partition.
Code:
String data_storage_root = mContext.getFilesDir().toString();
InputStream is= null;
OutputStream os = null;
File h = new File(data_storage_root+"/file.format");
if (h.exists()) h.setWritable(true, true);
try {
is = mContext.getResources().getAssets().open("keypad/file.format");
os = new FileOutputStream(data_storage_root+"/file.format");
IOUtils.copy(is, os);
is.close();
os.flush();
os.close();
os = null;
Log.d(TAG, "success copying");
} catch (IOException e) {
Log.w(TAG, "failed copying");
}
h.setExecutable(false, true);
h.setReadable(true, true);
h.setWritable(false, true);

Thanks for the info, I didn't know it!
When I use this code I have two issues, in mContext and IOUtils, what am I doing wrong?
And Copying from data to system I preffer doing it with RootTools. Can u help me pls??
Oh, sorry. This is a snipplet from one of my apps, it uses a library called commons-io-2.1.jar for the IOUtils. The context is just the context from the loader where this snipplet comes from.
I've never used RootUtils so I can't help you with that, sorry.
When I'm not on my phone but at a computer I'll search for an alternative to extract the file from the apk for you (if you haven't found it by then, SO will have an answer for sure).

This is all my code, I use your library and RootTool library.
I have two issues:
1- Error in waitForFinish();
2- processDialog don't appear.

Hi,
I've rewrote my snipplet not to use the apache library (eventually it is just one method that was used so this is more clean) and added that to a asynctask.
Better late than never now you have rewritten yours as well :S Attached is the eclipse project.
Also, in your code you are trying to copy two files, that is not going to work like that. You define the inputstream and the outputstream twice. I will make this thing work for you if you haven't figured it out tomorrow, will take 24 hrs for me to come back on this. I don't use roottools as I said but maybe I'll look into that as well. Else I will give you an alternative.

I'm frustrated... You change the name of my functions an now I don't understand anything.
public void reparar is the name of the button function, in your code the functions starts "onCreate".
I prefer my dirty but understable (for me) code
Now I have only one problem, the app works, but it take a long time to reemplace the file in system directory. In other words, I pulse the button, close the application, an in one minute the file is reemplaced. How can I fix that an take this time in a progress dialog?
Sorry for my bad english! I'm spanish

Hi, I haven't had time to produce more code for you.
Just some remarks looking at your code:
1 you duplicate a lot of code
2 your application does everything on the main thread
3 you do a lot of unnescasairy code on the terminal
1)
copyfle 1 and 2 are almost the same, why not use it only once? copyFile(String filename){ ... } for example?
2)
extracting the files form the apk to /data schould be done at the loading of the app, in the background and preferably only once (now it tis done everytime the app starts), then copy it to system at a press of the button. In my example there is a function doneBackground(boolean succes), from there you could set the visiblity of your button to View.VISIBLE, allowing the user to copy the file to /system, now everything is done after the button press.
3)
Code:
"su"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
"cp /data/data/com.fixer.gminipop/files/sec_key.kl /system/usr/keylayout/sec_key.kl"

"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system");
this calls 2 times su and it mounts 2 times the system as rw and back to ro, can hugely be optimized
Edit, just read Nikwens reply in your other thread, you don't have to call su at all according to him. However,as I said, I am not a user of Roottools so can't confirm that.

Hi, I haven't had time to produce more code for you.
Just some remarks looking at your code:
1 you duplicate a lot of code
2 your application does everything on the main thread
3 you do a lot of unnescasairy code on the terminal
1)
copyfle 1 and 2 are almost the same, why not use it only once? copyFile(String filename){ ... } for example?
2)
extracting the files form the apk to /data schould be done at the loading of the app, in the background and preferably only once (now it tis done everytime the app starts), then copy it to system at a press of the button. In my example there is a function doneBackground(boolean succes), from there you could set the visiblity of your button to View.VISIBLE, allowing the user to copy the file to /system, now everything is done after the button press.
3)
Code:
"su"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
"cp /data/data/com.fixer.gminipop/files/sec_key.kl /system/usr/keylayout/sec_key.kl"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system")
"su"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
"cp /data/data/com.fixer.gminipop/files/sec_keypad.kl /system/usr/keylayout/sec_keypad.kl"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system");

Thank's! I'm going to fix that, Optimice code and clear it. But the problem persist, the copy of the file to system take a long time, and the process to do it is after I close the app, This is my only important error..

You should get someone to translate all that Spanish to English. I took the effort to translate it for myself (with Google translator) but I'm sure the advantage potential user won't.

I see that you can write English.
However, you might want to have it translated to other languages, too.

Create the directory using the mkdir() method in the java.io.File class. And copy every file to the directory in /data/data. You need to copy the files one by one.

Remove that "su" in the CommandCapture. You tell the library that you want to be root by calling getShell() with the parameter true. The parameter true tells RootTools to call su itself.

But I have another problem, I'm developing an app to copy files from assets to system. The code works, but the copy from /data/data/.. to /system/... take a long time and I don't know how to put a progress dialog. But this problem is strange, becouse the copy of the file is abot a minute after I close the app. I want to make a progress dialog in this time. Can you help me??

I've answered your last question in your other thread and I would prefer not to use this thread anymore. If RootTools works without calling "su" implicitly, even better as su is expensive call!
Thread closed.
Currently, i'm making an application that involves using GestureOverlayView. I've already created some default gestures using the GestureBuilder and have copied them into my res/raw folder in my application. My application also does customization, meaning that the user can create his or her own gestures and save them. I've read that it's impossible for me to just save the additionally made gestures from the users to the res/raw folder. I was told that i have some optionals: ExternalStorage (to SD card), InternalStorage, and SharedPreferences. Which method is probably the more optimal choice?
I've tried using these codes:
gestureLib.addGesture(scName.getText().toString(), gesture);
gestureLib.save();
setResult(RESULT_OK);
in an attempt to save them. Even though the gestures do save, but when i restart the application, they're gone. Please help! Thanks so much!

I haven't used gestures so far but for the saving:
In your SharedPreferences you can only save the standard types like int or string. I'm guessing you don't want to convert the gesture to string and backwards, so I'd say external storage in a folder with the name of your app(so the user can manually delete it) but you could also save the file in your app directory.
Look at This question , he uses the gesture library and saves it to the file with
Code:
GestureLibrary store = GestureLibraries.fromFile(mStoreFile);
store.addGesture("Gesture Password", mGesture);
store.save();
My application successfully saves now, but there's still a consistent problem. When i restart the application, the saved gestures are gone. Why is that?

When you restart your app, everything in its ram will be gone, so you always need to load the saved file and then import the gestures to the library again probably.
You'd want to do that in the onCreate() or onRestart().
In the above example,
Code:
store.load();
Is used to do that
It works now. Thanks a lot. I'm assuming that these gestures are being saved in the application itself, since that i can't find them in the SD card. Thanks for your time, by the way.

BUMP! I've been struggling with a problem that i newly encountered. What i want to do is, i want to create a folder in the external directory and save ALL the gestures that the user creates. But the thing is, every time i save the gesture, it overwrites the existing one. How do i create a folder and put the new ones in it? Any help or hints would be nice

You've got to use a different string for every gesture in that line:
Code:
store.addGesture("this should be a different string every time", mGesture);
Then you should be able to put them into one file.

As far as I know the file you save it to mustn't be a directory, but a file.
Try that:
Code:
mStoreFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/com.epicunlock.rx24race");
if (!mStoreFile.exists()) {
mStoreFile.mkdirs();
}
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]
lib.load();
and
Code:
if (!found) {
Log.v("TAG", "Gesture has been saved");
Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show();
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]

As far as I know the file you save it to mustn't be a directory, but a file.
Try that:
Code:
mStoreFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/com.epicunlock.rx24race");
if (!mStoreFile.exists()) {
mStoreFile.mkdirs();
}
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]
lib.load();
and
Code:
if (!found) {
Log.v("TAG", "Gesture has been saved");
Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show();
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]
lib.addGesture(scName.getText().toString(), gesture);
lib.save();
setResult(RESULT_OK);

I've tried something similar to this before too, but the same problem still exists. it keeps overwriting the previous one. It's never able to save multiple gestures.
What i have:
Code:
package com.epicunlock.rx24race;
import java.io.File;
import java.util.ArrayList;
import android.app.Activity;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.gesture.Prediction;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.EditText;
import android.widget.Toast;
public class createShortcut extends Activity implements
OnGesturePerformedListener {
boolean found = false;
EditText scName;
GestureOverlayView gestures;
GestureLibrary lib, storage;
File path;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.createshortcutlayout);
scName = (EditText) findViewById(R.id.etName);
gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
path = new File(Environment.getExternalStorageDirectory() + "/Android/data/com.epicunlock.rx24race/");
if (!path.exists()) {
path.mkdirs();
}
File gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
lib.load();
}
[user=439709]@override[/user]
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
// TODO Auto-generated method stub
found = false;
ArrayList<Prediction> predictions = lib.recognize(gesture);
for (String s : lib.getGestureEntries()) {
Log.v("GESTURE", s);
}
Log.v("TAG", "Gesture has been detected");
for (Prediction p : predictions) {
Log.v("TAG", p.toString());
Log.v("^ Score", "" + p.score);
}
for (Prediction p : predictions) {
if (p.score > 2.0) {
Toast.makeText(this, p.name, Toast.LENGTH_SHORT).show();
found = true;
}
}
if (!found) {
Log.v("TAG", "Gesture has been saved");
Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show();
File gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
lib.addGesture(scName.getText().toString(), gesture);
lib.save();
setResult(RESULT_OK);
}
}
}
I just fixed the problem: "Can't save multiple gestures."
This is how i fixed it. But can anyone tell me what difference it made?
Code:
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.createshortcutlayout);
scName = (EditText) findViewById(R.id.etName);
gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
path = new File(Environment.getExternalStorageDirectory() + "/Android/data/com.epicunlock.rx24race/");
if (!path.exists()) {
path.mkdirs();
}
[B]if (lib == null) {
gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
}[/B]
lib.load();
}
Moderators... It says I am breaking the rules by asking a question and to ask in the Q&A... But the title of this is "Coding Discussion, Q&A, and Educational Resources" I am not breaking the rules intentionally, I just don't know where else to put this. This is a Coding Question, not a General Question that I would think would get buried and or lost in the General Q&A forum. Please move if you feel I am incorrect.
Hello All, I was hoping someone could help me.
I am trying to create an app that will hide pictures. I want to be able to Pick my App from the Share (Send To) menu from the Users Gallery and have it copy the file to a Directory I have created on my SDCard and then ultimately delete the file from the current location.
Here is what I have so far, but when I pick my app from the Share menu, it crashes the Gallery app. So... I can't even see any errors in my LogCat to even try and troubleshoot my issue.
Can someone point me to a working example of how to do this (I have searched the internet until I am blue in the face) or... I hate to say it... Fix my Code?
Any Help would be appreciated... Thanks!!

What's the gallery log output?
Btw, you're not breaking the rules. This is the right forum for Java Q&A.

How would I get the Logs for the Gallery? I am using and HTC ONE and it's the standard Gallery. Nothing shows up in LogCat so I'm stuck

Do you view the logs on your computer?
There should be an error message in the logs.

Which Logs?? As I said before. LogCat does not give any errors.
