Widget not working - Java for Android App Development

Widget not working - Java for Android App Development

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:
Code:
package com.example.increment;
import android.app.IntentService;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
public class AppWidget extends AppWidgetProvider {
int c = 0;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction() == null)
context.startService(new Intent(context, ToggleService.class));
else
super.onReceive(context, intent);
}
[user=439709]@override[/user]
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
private class ToggleService extends IntentService {
public ToggleService() {
super("AppWidget$ToggleService");
// TODO Auto-generated constructor stub
}
[user=439709]@override[/user]
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
ComponentName me = new ComponentName(this, AppWidget.class);
AppWidgetManager mgr = AppWidgetManager.getInstance(this);
mgr.updateAppWidget(me, buildUpdate(this));
}
private RemoteViews buildUpdate(Context context) {
// TODO Auto-generated method stub
RemoteViews rm = new RemoteViews(context.getPackageName(),
R.layout.widget);
c++;
String s = String.valueOf(c);
rm.setTextViewText(R.id.t2, s);
Intent i = new Intent(this, AppWidget.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
rm.setOnClickPendingIntent(R.id.t2, pi);
return rm;
}
}
}
THE WIDGET.XML
Code:

android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView
android:id="@+id/t2"

[Q] App that start when boot of the phone is complete

Hi boys,
I'm a novice android programmer.
I want to create an app that start when the boot of the phone is complete.
I've write this code, the application work if I click on the icon, but it don't work when the boot of the phone is complete!!
this is my code:
Code:
public class HelloMyBoss extends Activity implements TextToSpeech.OnInitListener{
private TextToSpeech tts;
private String sayd;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
sayd="";
tts= new TextToSpeech(this, this);
}
@Override
protected void onDestroy() {
// Don't forget to shutdown!
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
@Override
public void onInit(int status) {
// status can be either TextToSpeech.SUCCESS or TextToSpeech.ERROR.
if (status == TextToSpeech.SUCCESS) {
// Set preferred language
int result = tts.setLanguage(Locale.ITALY);
if (result == TextToSpeech.LANG_MISSING_DATA ||
result == TextToSpeech.LANG_NOT_SUPPORTED) {
// Lanuage data is missing or the language is not supported.
Log.e(TAG, "Language is not available.");
} else {
sayHello();
}
} else {
// Initialization failed.
/Log.e(TAG, "Could not initialize TextToSpeech.");
}
}
private void sayHello() {
String hello = "Buon Giorno! Mi sono appena acceso...";
tts.speak(hello,
TextToSpeech.QUEUE_FLUSH, // Drop all pending entries in the playback queue.
null);
}
}
Code:
public class MyIntentReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent arg1) {
Intent startupBootIntent = new Intent(context, HelloMyBoss.class);
startupBootIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startupBootIntent);
}
}
...and this is my manifest:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="mrbrown.android.hellomyboss"
android:versionCode="1"

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!

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:

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?
