i've need to connect my app to an external database so i put my sqlite database on assets folder and i've follow this tutorial to make DBHelper.
now i want to show some record of database in my app but when i launch it, it give me an error like a table "linee" doesn't exists on my database but it exists!!!! this link cans proof it http://img689.imageshack.us/img689/926/ytvo.png
why???? it's a week that i can to fix this problem but i can't solve it
this is MyOpenHelper
Code:
public class MyOpenHelper extends SQLiteOpenHelper{
//The Android's default system path of your application database.
private static String DB_PATH ;

} else {
DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";
}
this.myContext = context;
}
public void createDataBase() throws IOException{

this.getReadableDatabase();
try{

Hi everyone.
I want to retrieve the current cpu frequency in my app but I don't seem to be right.
In my code I want to read the "scaling_cpu_freq" file from internal storage.
This is the code:
Code:
private String ReadCPUMhz() {
String cpuMaxFreq = "";
int cur = 0;
try {
[user=1299008]@supp[/user]ressWarnings("resource")
BufferedReader maxi = new BufferedReader(new FileReader(new File("/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq")));
try{
cpuMaxFreq = maxi.readLine();
cur = Integer.parseInt(cpuMaxFreq);
cur = cur/1000;
} catch (Exception ex){
ex.printStackTrace();
}
} catch (FileNotFoundException f) {
f.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return String.valueOf(cur);
}
The problem is that the method only returns 0, which is the initial value of the int "cur".
Can anybody help me?
Thanks in advance.
Here's the code I use:
Declare this class in your Activity
Code:
// Read current frequency from /sys in a separate thread
// This class assumes your TextView is declared and referenced in the OnCreate of the class this one is declared in
// And its variable name is mCurCpuFreq
protected class CurCPUThread extends Thread {
private static final String CURRENT_CPU = "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq";
private boolean mInterrupt = false;
public void interrupt() {
mInterrupt = true;
}
[user=439709]@override[/user]
public void run() {
try {
while (!mInterrupt) {
sleep(400);
final String curFreq = readOneLine(CURRENT_CPU);
mCurCPUHandler.sendMessage(mCurCPUHandler.obtainMessage(0,
curFreq));
}
} catch (InterruptedException e) {
return;
}
}
}
// Update real-time current frequency & stats in a separate thread
protected static Handler mCurCPUHandler = new Handler() {
public void handleMessage(Message msg) {
mCurFreq.setText(toMHz((String) msg.obj));
final int p = Integer.parseInt((String) msg.obj);
new Thread(new Runnable() {
public void run() {
// Here I update a real-time graph of the current freq
}
}
}).start();
}
};
Helper methods used :
Code:
// Convert raw collected values to formatted MhZ
private static String toMHz(String mhzString) {
if (Integer.valueOf(mhzString) != null)
return String.valueOf(Integer.valueOf(mhzString) / 1000) + " MHz";
else
return "NaN";
}
// Iterate through the /sys file
public static String readOneLine(String fname) {
BufferedReader br;
String line = null;
try {
br = new BufferedReader(new FileReader(fname), 512);
try {
line = br.readLine();
} finally {
br.close();
}
} catch (Exception e) {
Log.e(TAG, "IO Exception when reading sys file", e);
// attempt to do magic!
return readFileViaShell(fname, true);
}
return line;
}
// Backup method if the above one fails
public static String readFileViaShell(String filePath, boolean useSu) {
CommandResult cr = null;
if (useSu) {
cr = new CMDProcessor().runSuCommand("cat " + filePath);
} else {
cr = new CMDProcessor().runShellCommand("cat " + filePath);
}
if (cr.success())
return cr.getStdout();
return null;
}

Sorry for the unclear title. What I'm trying to do is the following:
Code:
Button btncheat = (Button) findViewById(R.id.button1);
final EditText score = (EditText) findViewById(R.id.editText1);
btncheat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String filename = "FlappyBird.xml";
String string = "<?xml version='1.0' encoding='utf-8' standalone='yes' ?>\n<map>\n<int name=\"score\" value=\"" + score.getText().toString() + "\" />\n</map>";
FileOutputStream outputStream;
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
String[] commands = {"mv /data/data/de.aciid.nullgc/files/FlappyBird.xml /data/data/com.dotgears.flappybird/shared_prefs/"};
RunAsRoot(commands);
} catch (Exception e) {
e.printStackTrace();
}
}
});
So, it creates the XML file from the String "string" (I don't know if I can do it like this, but the XML file looks right in the end) and move it to /data/data/com.dotgears.flappybird/shared_prefs/. The creation and moving of the XML file works flawless, but Flappy Bird does not read the pref properly. When I start the game, it says that my highscore is zero, although the score 999 (for example) is in the XML file. As I stated, the XML file looks right, I pasted an original and my modded XML in an online script and there are no differences whatsoever.
So why doesn't this work?
Hi. I´m from Germany. Sorry for my bad English.
On my Work, there is a Server with Wlan. The Page on this Server is like a Forum (Like XDA).
I´m a beginner in Android, but my app is 90% finish.
Now my Problem. In the Forum page there is "like XDA" an upload button. I have make my Filechooser but there is the problem. When i upload test.pdf or test.bmp. Server says ok, name of the file is test.pdf or test.bmp. So i can upload
My problem is only with jpg. When Filechooser open and i choose the jpg (sdcard0 oder extsdcard) the name on the server gives the picture a number. That means test.jpg = 1983 . Can´t upload.
I hope you understand me, and can give me a fix. Thanks for Help!!!

When I import "uri" for my on activity results at the end of my code I get a bunch of errors for everything I'm doing with parse. I been searching and trying different image picker tutorials and always end up with same results. I've checked out parse.com but only see info on saving images from the drawable folder. If I can get the image picker to work I'm pretty sure I can figure out how to save it to parse.com.
