Hey there. i was experimenting with intents.. While I got stuck in this bug. I am almost positive, that my java classes have been coded correctly...
I think, its the android manifest.. The intent filters have not been setup correctly... However I will be posting.. all of my code and the logcat here...
Please help me.. Thanks in advance!

OK, so first of all, in your manifest, you do not need to create an intent-filter, that is just if an activity needs to be launched from another application.
Then, when you create your Intent to start the SecondActivity, do it like this:
Code:
Intent i = new Intent(this, SecondActivity.class);
// put extras and startforResult here
The Error in the logcat states that it could not find the activity, so I suppose this is why

Code:
<activity
android:name="com.example.intents.SecondActivity"
android:label="@string/app_name" >
<intent-filter>
[B]<action android:name="[COLOR="Red"]android.intent.action.SecondActivity[/COLOR]" />[/B]
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
The bold should be referencing the same intent you are trying to call. Change the red text portion above to "com.example.intents.SecondActivity" and use the same to call the intent.
example: Intent i = new Intent("com.example.intents.SecondActivity");
The red text should match each other.

Still crashing!

I changed the code, as you said.. But it is still not working...
I am uploading the manifest, and the MainActivity.java again..

Toast.LENGTH_SHORT).show();
Toast.makeText(this, data.getData().toString(),
Toast.LENGTH_LONG).show();
}
}
}
}

It is giving errors because of how you are trying to get the strings from the intent in SecondActivity.
replace what you have in your SecondActivity onCreate with the below.
Code:
Intent intent = getIntent();
Toast.makeText(this, intent.getStringExtra("str1"), Toast.LENGTH_LONG).show();
Toast.makeText(this, String.valueOf(intent.getIntExtra("age1", 0)), Toast.LENGTH_LONG).show();
Bundle bundle = intent.getExtras();
Toast.makeText(this, bundle.getString("str2"), Toast.LENGTH_SHORT)
.show();
Toast.makeText(this, Integer.toString(bundle.getInt("age2")),
Toast.LENGTH_SHORT).show();

Thank you, finally it worked :thumbup:

Widget not working

Hey, fellas.. I was learning about widgets. But I got stuck at the very beginning. I was trying to make the simplest of a widget. Firstly, I made an app, that only has one textview on it. When clicked , it shows the number of times it has been clicked. Then I tried to make a widget of the same.
But when I click over the widget, nothing happens. It just shows the initialized number '0'. The debugging goes fine. There is no ANR errors.
But I am not able to figure out the logical error. As the debugging goes alright, I don't think, the logcat will be necessary.
However, If required , I will provide it too. For now, I am uploading the AppWidget.class, widget.xml, manifest.xml, widget_provider.xml :::
THE APPWIDGET.CLASS:

2.3.3 to 4.2.2 Http Get - Help me conquer learning curve

Hey all!
New to Android but not developing. App runs great with emulator running Android 2.3.3. When I install the app to my phone (Samsung Galaxy 4S Active) runnnig Android 4.2.2, the Http Get execute command on the client does not seem to happen. I get no data back reported to my TextView.
I know there is some learning curve I'm missing here, and would appreciate some guidance.
HttpExample.java
Code:
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HttpExample extends Activity {
TextView httpStuff;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.httpex);
httpStuff = (TextView) findViewById(R.id.tvHttp);
GetMethodEx test = new GetMethodEx();
try {
String returned = test.getInternetData();
httpStuff.setText(returned);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
GetMethodEx.java
Code:
package com.example.test;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URI;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class GetMethodEx {
public String getInternetData () throws Exception {
BufferedReader in = null;
String data = null;
try {
HttpClient client = new DefaultHttpClient();
URI website = new URI("CANTPOSTURL");
HttpGet request = new HttpGet();
request.setURI(website);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String l = "";
String nl = System.getProperty("line.separator");
while ((l = in.readLine()) !=null) {
sb.append(l + nl);
}
in.close();
data = sb.toString();
return data;
}finally {
if (in !=null) {
try {
in.close();
return data;
}catch (Exception e) {
e.printStackTrace();
}
}
}
}
}
AndroidManifest.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="CANTPOSTURL"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application

android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
httpex.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="CANTPOSTURL"
xmlns:tools="CANTPOSTURL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".HttpActivity">
<ScrollView android:layout_height="fill_parent" android:layout_width="fill_parent">
<TextView
android:id="@+id/tvHttp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Loading Data" >
</TextView>
</ScrollView>
</LinearLayout>
I would post the logcat but there really is no issue at 2.3.3... just need to know what i'm missing going to 4.2.2.
Thanks in advance, I know this should be easy for you all.

can't send message from wear to my phone app

I want to send data from my wear to the phone app.
I've created a phone app with this AndroidManifest.xml:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="sh.evolutio.car">
<uses-feature
android:name="android.software.leanback"
android:required="true" />
<application
android:allowBackup="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<service android:name=".services.ListenerService" >
<intent-filter>
<action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" />
<action android:name="com.google.android.gms.wearable.DATA_CHANGED" />
<!-- <data android:scheme="wear" android:host="*" android:pathPrefix="/updatecar" /> -->
</intent-filter>
</service>
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.LEANBACK_LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
my Phone ListenerService:
Code:
package sh.evolutio.car.services;
import android.content.Intent;
import android.util.Log;
import com.google.android.gms.wearable.MessageEvent;
import com.google.android.gms.wearable.WearableListenerService;
public class ListenerService extends WearableListenerService {
private static final String TAG = "ListenerService";
private static final String MESSAGE_PATH = "/updatecar";
@Override
public void onCreate() {
Log.d(TAG, "ListenerService created");
}
@Override
public void onMessageReceived(MessageEvent messageEvent) {
Log.d(TAG, "onMessageReceived");
if (messageEvent.getPath().equals(MESSAGE_PATH)) {
Log.d(TAG, "good message");
} else {
Log.d(TAG, "bad message");
}
}
}
my MainActivity with this onCreate:
Code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
startService(new Intent(MainActivity.this, ListenerService.class));
}
When I start the App on my phone I got in the Logcat:
Code:
26131-26131/sh.evolutio.car D/ListenerService: ListenerService created
When I send with the wearapp some data to my phone, my ListenerService didn't fire the onMessageReceived method..
Here is my AndroidManifest from the wearapp:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="sh.evolutio.carwear">
<uses-feature android:name="android.hardware.type.watch" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@android:style/Theme.DeviceDefault">
<uses-library
android:name="com.google.android.wearable"
android:required="true" />
<meta-data
android:name="com.google.android.wearable.standalone"
android:value="false" />
<activity
android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
The MainActivity from the wearapp looks like this:
Code:
package sh.evolutio.carwear;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.wearable.activity.WearableActivity;
import android.util.Log;
import android.view.View;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.tasks.OnFailureListener;
import com.google.android.gms.tasks.OnSuccessListener;
import com.google.android.gms.tasks.Task;
import com.google.android.gms.wearable.MessageApi;
import com.google.android.gms.wearable.Node;
import com.google.android.gms.wearable.NodeApi;
import com.google.android.gms.wearable.Wearable;
public class MainActivity extends WearableActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static String TAG = "MainActivity";
private static final String MESSAGE_PATH = "/updatecar";
Node mNode; // the connected device to send the message to
GoogleApiClient mGoogleApiClient;
private boolean mResolvingError = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Connect the GoogleApiClient
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
sendMessage("test");
// Enables Always-on
setAmbientEnabled();
}
@Override
protected void onStart() {
super.onStart();
if (!mResolvingError) {
mGoogleApiClient.connect();
}
}
/**
* Resolve the node = the connected device to send the message to
*/
private void resolveNode() {
Log.d(TAG, "resolveNode");
Wearable.NodeApi.getConnectedNodes(mGoogleApiClient)
.setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
@Override
public void onResult(NodeApi.GetConnectedNodesResult nodes) {
for (Node node : nodes.getNodes()) {
Log.d(TAG, "resolvedNode: " + node);
mNode = node;
}
}
});
}
@Override
public void onConnected(Bundle bundle) {
resolveNode();
}
@Override
public void onConnectionSuspended(int i) {}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d(TAG, "connectionResult: " + connectionResult);
}
/**
* Send message to mobile handheld
*/
private void sendMessage(String Key) {
if (mNode != null && mGoogleApiClient!= null && mGoogleApiClient.isConnected()) {
final String messageKey = Key;
Log.d(TAG, "isConnected: " + mGoogleApiClient.isConnected());
Log.d(TAG, "connected to: " + mNode.getId());
Task<Integer> sendTask = Wearable.getMessageClient(MainActivity.this).sendMessage(mNode.getId(), MESSAGE_PATH, messageKey.getBytes());
sendTask.addOnSuccessListener(new OnSuccessListener<Integer>() {
@Override
public void onSuccess(Integer integer) {
Log.d(TAG, "onSuccess: " + integer);
}
});
sendTask.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, "onFailure: " + e.getMessage());
}
});
Wearable.MessageApi.sendMessage(mGoogleApiClient, mNode.getId(), MESSAGE_PATH, messageKey.getBytes()).setResultCallback(
new ResultCallback<MessageApi.SendMessageResult>() {
@Override
public void onResult(@NonNull MessageApi.SendMessageResult sendMessageResult) {
if (sendMessageResult.getStatus().isSuccess()) {
Log.v(TAG, "Message: { " + messageKey + " } sent to: " + mNode.getDisplayName());
} else {
// Log an error
Log.v(TAG, "ERROR: failed to send Message");
}
}
}
);
}
}
}
When I the message got send, i got this in the logcat from the wearapp:
Code:
sh.evolutio.carwear D/MainActivity: isConnected: true
sh.evolutio.carwear D/MainActivity: connected to: 778d0d53
sh.evolutio.carwear V/MainActivity: Message: { forward } sent to: HUAWEI Mate 10 Pro
sh.evolutio.carwear D/MainActivity: onSuccess: 17282
so the message was sent to my Mate 10 Pro. But why my Mate 10 Pro App can't receive the Message?
