I have two app - MyApplication and FirstApp. There's is a button in MyApplicaton on click of which I am navigated to FirstApp.
Now, I want to read the contents of FirstApp using AccessibilityService.
My code goes like this for MyApplication-
MainActivity.java
package com.example.abc.myapplication;
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private Button mButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(this,MyAccessibilityService.class);
startService(intent);
mButton = (Button) findViewById(R.id.click_me);
mButton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.example.abc.firstapp");
startActivity(launchIntent);
}
}
MyAccessibilityService.java
package com.example.aayushi.myapplication;
public class MyAccessibilityService extends AccessibilityService {
private AccessibilityServiceInfo info;
#Override
protected void onServiceConnected() {
Log.i("service connected","service");
info = new AccessibilityServiceInfo();
info.eventTypes=AccessibilityEvent.TYPES_ALL_MASK;
info.notificationTimeout=100;
info.feedbackType=AccessibilityEvent.TYPES_ALL_MASK;
info.packageNames = new String[]{"com.example.abc.firstapp"};
setServiceInfo(info);
}
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
Log.i("onEvent----","yay");
Log.i("event-----------", event.toString());
//Log.i("source", event.ge)
}
#Override
public void onInterrupt() {
}
}
AndroidManifest.xml

The problem is after enabling accessibility on device, onServiceConnected() is not at all getting called.
For testing, I am using Android 8.0.0 , API 26.
It looks like you're trying to start your accessibility service from within your activity. You can't do this. You must start your accessibility service from the accessibility services menu. Settings > General > Accessibility. You also most get rid of the code that attempts to start your service from within your activity.

I have a PackageBroadcastReceiver running ok while the app is in the background. I need it to keep listening to packages added/removed when it is closed. But, it is not.
Is there any way to do this with a BroadcastReceiver or should I move to a service?
Here the code:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="23" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.cresan.antivirus.StockingActivity"
android:label="#string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="com.tech.applications.coretools.advertising.PackageBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_INSTALL" />
<action android:name="android.intent.action.PACKAGE_ADDED" />
<data android:scheme="package"/>
</intent-filter>
</receiver>
</application>
And my PackageBroadcastReceiver:
public class PackageBroadcastReceiver extends BroadcastReceiver
{
static IPackageChangesListener _listener;
static public void setPackageBroadcastListener(IPackageChangesListener listener)
{
_listener=listener;
}
#Override
public void onReceive(Context ctx, Intent intent)
{
if(_listener!=null && Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction()))
_listener.OnPackageAdded(intent);
if(_listener!=null && Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction()))
_listener.OnPackageRemoved(intent);
}
}
Cheers.
You will definitely need to implement a background service to do this. See the developer guide.
You can then programmatically register a BroadcastReceiver in your service:
private PackageBroadcastReceiver packageBroadcastReceiver;
#Override
public void onCreate() {
super.onCreate();
this.packageBroadcastReceiver = new PackageBroadcastReceiver();
this.packageBroadcastReceiver.setPackageBroadcastListener(new IPackageChangesListener() {
public void OnPackageAdded(Intent i) {
//do something here- probably start an activity
}
...
});
IntentFilter packageFilter = new IntentFilter("android.intent.action.PACKAGE_ADDED");
packageFilter.addAction("android.intent.action.PACKAGE_INSTALL");
packageFilter.addDataScheme("package");
this.registerReceiver(this.packageBroadcastReceiver, packageFilter);
}
#Override
public void onDestroy(){
super.onDestroy();
this.unregisterReceiver(this.packageBroadcastReceiver);
}
Try registering broadcast receiver in service. After activity is destroyed, receiver will be destroyed to so you will not get broadcast event.
I am trying go from one activity to its sub-activity (i.e, a new page with more buttons), but every time I click the button, the application "Unfortunately stops running".
I believe that the flaw lies in the manifest where I might writing something wrong under the intent-filter section.
Mind taking a look?
public class MainActivity extends ActionBarActivity {
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
addListenerOnButton2();
}
//First Activity
private void addListenerOnButton() {
// TODO Auto-generated method stub
button = (Button) findViewById(R.id.activity_one);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent IntentOne =
new Intent(arg0.getContext(), ActivityOne.class);
arg0.getContext().startActivity(IntentOne);
}
});
}
//Second Activity, will look into it later. Making it Explicit for now.
public void addListenerOnButton2() {
button = (Button)findViewById(R.id.activity_two);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View argo) {
Intent IntentTwo = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.ca"));
startActivity(IntentTwo);
}
});
}
}

I have not added ActivityTwo yet to the manifest.
You can't have Activities that aren't registered in the Manifest. I don't see an ActivityOne registered in your AndroidManifest.xml
What I want is : I want to run an application without LAUNCHER ICON and BraodCastReceiver running in the background. I searched And Make a DEMO for it
Result of this : Launcher ICON gone but when I reboot the phone BroadCastReceiver dosen't run. What is the possible Solution for this. I added the code what I am trying.
MainActivity
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(MainActivity.this, MyBroadcastReceiver.class);
sendBroadcast(intent);
PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(),PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}
BroadCastReceiver Class
public class MyBroadcastReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "hahahah", Toast.LENGTH_LONG).show();
}
}
Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Try this...

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(),PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
finish();
}
I m trying to start an IntentService from the main activity of y application and it won't start. I have the service in the manifest file. Here's the code:
MainActivity
public class Home extends Activity {
private LinearLayout kontejner;
IntentFilter intentFilter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
kontejner = (LinearLayout) findViewById(R.id.kontejner);
intentFilter = new IntentFilter();
startService(new Intent(getBaseContext(), HomeService.class));
}
}
Service:
public class HomeService extends IntentService {
public HomeService() {
super("HomeService");
// TODO Auto-generated constructor stub
}
#Override
protected void onHandleIntent(Intent intent) {
Toast.makeText(getBaseContext(), "TEST", Toast.LENGTH_LONG).show();
}
}
Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.salefinder"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Home"
android:label="#string/title_activity_home" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".HomeService" />
</application>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
How can I make it work?
onHandleIntent gets called from a background thread. You can't modify the UI, or in this case, make Toast from outside the UI thread. So, I wouldn't expect anything to happen with your service.
Just try writing something out with Log.d() to see if your service is getting called.
It seams that android cached a bad version of the app - I forced closed it and started it again, and it worked...
In my application I need to process physical button events such as volume button clicks. For that I'm using audiomanager's registerMediaButtonEventReceiver method. There's an article relevant to my situation, though I can't get it working.
Here's code I'm using:
public class VolumeBroadcastActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AudioManager manager = (AudioManager) getSystemService(AUDIO_SERVICE);
manager.registerMediaButtonEventReceiver(new ComponentName(getPackageName(), RemoteControlReceiver.class.getName()));
}
public class RemoteControlReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(VolumeBroadcastActivity.this, "1",1).show();
if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {
}
}
}
}
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="localhost.volume.broadcast"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".VolumeBroadcastActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="RemoteControlReceiver">
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>
</application>
</manifest>
Your RemoteControlReceiver class is an inner class of VolumeBroadcastActivity. Your manifest doesn't say so and I don't think it could. Make it a regular class and precede its android:name with a dot.
You might need this permission (declare in manifest):
uses-permission android:name="android.permission.BLUETOOTH"
