How to remove icon programatically (Android) - android

By remove the below intent-filter in AndroidManifest.xml, it can remove the icon after install.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
But i have try the below when on Boot than remove the Icon, but the icon still remain after reboot. I have add the permission, and this reboot receiver is work.
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
PackageManager p = context.getApplicationContext().getPackageManager();
ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity");
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}
}
Or Put the Boot on service and AndroidManifest.xml intent-filter is not remove, the service is run and work.
package com.example.removeicon;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity");
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
startService();
}

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity");
p.setComponentEnabledSetting(componentName,
PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
Note that the icon may not be gone until the next reboot.

try this below code, this one worked for me
PackageManager p = ctx.getPackageManager();
p.setComponentEnabledSetting(((Activity)ctx).getComponentName(),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

How can I programmatically hide app icon after the installation in android , then access thru secret code like *#*#numbers*#*#?

I am new to android programming and I want my app to hide application icon after installation. I will use the code for my thesis. Thank you.
First, you have to make a receiver like this..
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
if (LAUNCHER_NUMBER.equals("**11**")) {
PackageManager p = context.getPackageManager();
ComponentName componentName = new ComponentName(context, MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
} else if (LAUNCHER_NUMBER.equals("**22**")) {
ComponentName componentToEnable = new ComponentName(getApplicationContext(), MainActivity.class);
PackageManager pm = getApplicationContext().getPackageManager();
pm.setComponentEnabledSetting(componentToEnable, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
}
}
}
Add this Permission to manifest.
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
Register it to manifest file.
<receiver android:name=".MyReceiver" >
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
Enjoy Coding...

If you don't want to have a launcher icon on your app just don't put the "LAUNCHER" category in any activity of the "AndroidManifest.xml" file. The category looks like this:
<category android:name="android.intent.category.LAUNCHER" />
Remove
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
From your manifest for all activities.

Widget doesn't launch service when being clicked

I'm creating a widget for my app but it refuses to work.
This widget launching an configuration activity when it's being created, and when you click it, it should start a IntentService I've created.
But when I click it, it doesn't start the service! I tried to change this pending intent to an intent that would launch Google and it works.
Some code:
AppWidgetProvider XML
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:configure="com.eladaharon.android.lary.widget.LaryWidgetConfigurationActivity"
android:initialLayout="#layout/widget_1x1"
android:minHeight="72dp"
android:minWidth="72dp"
android:updatePeriodMillis="86400000" >
</appwidget-provider>
Manifest declaration
<activity
android:name=".widget.LaryWidgetConfigurationActivity"
android:configChanges="orientation|keyboard" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
</intent-filter>
</activity>
<service android:icon="#drawable/icon" android:enabled="true" android:name="widget.LaryWidgetCheckService" />
<!-- Broadcast Receiver that will process AppWidget updates -->
<receiver android:name=".widget.LaryWidgetProvider" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="android.appwidget.action.APPWIDGET_DELETED" />
<action android:name="android.appwidget.action.APPWIDGET_ENABLED" />
<action android:name="android.appwidget.action.APPWIDGET_DISABLED" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/widget_provider" />
</receiver>
AppWidgetProvider class
public class LaryWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch service
Intent intent = new Intent(context, LaryWidgetCheckService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_1x1);
views.setOnClickPendingIntent(R.id.widget_check_button, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
public void onEnabled(Context context) {
PackageManager pm = context.getPackageManager();
pm.setComponentEnabledSetting(
new ComponentName("com.eladaharon.android.lary.widget",
".SalaryWidgetConfigurationActivity"),
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);
}
public void onDisabled(Context context) {
PackageManager pm = context.getPackageManager();
pm.setComponentEnabledSetting(
new ComponentName("com.eladaharon.android.lary.widget",
".LaryWidgetConfigurationActivity"),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
}
public void onDeleted(Context context, int[] appWidgetIds)
{
Editor edit = context.getSharedPreferences(Constants.PREFERNCES_WIDGET_PREFERENCES, Context.MODE_PRIVATE).edit();
final int N = appWidgetIds.length;
for (int i=0; i<N; i++)
{
edit.remove(String.valueOf(appWidgetIds[i]));
}
edit.commit();
}
public static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
// Create an Intent to launch service
Intent intent = new Intent(context, LaryWidgetCheckService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_1x1);
views.setOnClickPendingIntent(R.id.widget_check_button, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
Handler that being called on the configuration activity end
private Handler mHandler = new Handler(){
#Override
public void handleMessage(Message msg){
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(LaryWidgetConfigurationActivity.this);
LaryWidgetProvider.updateAppWidget(LaryWidgetConfigurationActivity.this, appWidgetManager,
mAppWidgetId);
// Make sure we pass back the original appWidgetId
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
};
The service I want to run on click
public class LaryWidgetCheckService extends IntentService {
private int mAppWidgetId;
public LaryWidgetCheckService(String name) {
super("WorkplaceService");
}
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
}
// If they gave us an intent without the widget id, just bail.
if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
return;
}
// Running some code
}
}
Thanks in advance!!
I hate this world!!!
If you'll look again in the manifest you can notice that I wrote widget.SERVICENAME instead of .widget.SERVICENAME!!!
I've Spent a whole day on this!
Thanks for everyone who tried to help!
Widget runs in another process, and you are sending an explicit intent that will works only inside your application. The reason of why the intent to launch google page in the web browser is because this is another type of intent that will involve broadcast receiver and it's propagated system wide to see if someone responds.
I think that you must declare a broadcast receiver in your service and fire that intent from your widget.

Hide application icon

I am doing an Android application. I want to hide the application icon in the emulator and I want to start my application by pressing some numbers, for instance 456#. Is there a way to do this?
To Hide app icon from launcher programatically you can do this
PackageManager packageManager = context.getPackageManager();
ComponentName componentName = new ComponentName(context,
LauncherActivity.class);
packageManager.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
To launch app by pressing number
first add folowing permission in mainfest file
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
Then register receiver
<receiver android:name=".LaunchAppViaDialReceiver">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
</intent-filter>
</receiver>
Then create a receiver class
public class LaunchAppViaDialReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
if (null == bundle)
return;
String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
//here change the number to your desired number
if (phoneNubmer.equals("12345")) {
setResultData(null);
Gaurdian.changeStealthMode(context,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED);
Intent appIntent = new Intent(context, LauncherActivity.class);
appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(appIntent);
}
}
If you want to hide the app icon it's a good idea to show the icon first and let the user know how to start the app once the icon is gone. First create an activity-alias in the manifest and move your intent filter there. This way you can disable the icon without disabling the activity.
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
</activity>
<activity-alias
android:name=".Launcher"
android:targetActivity=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity-alias>
Get the component name of the launcher alias using your package name:
private static final ComponentName LAUNCHER_COMPONENT_NAME = new ComponentName(
"your.package.name", "your.package.name.Launcher");
You can check if it's already disabled...
private boolean isLauncherIconVisible() {
int enabledSetting = getPackageManager()
.getComponentEnabledSetting(LAUNCHER_COMPONENT_NAME);
return enabledSetting != PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
}
...and disable it when appropriate after giving the user information:
private void hideLauncherIcon() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Important!");
builder.setMessage("To launch the app again, dial phone number 12345.");
builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
getPackageManager().setComponentEnabledSetting(LAUNCHER_COMPONENT_NAME,
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
}
});
builder.setIcon(android.R.drawable.ic_dialog_alert);
builder.show();
}
To launch from the dialer create a broadcast receiver:
public class LaunchViaDialReceiver extends BroadcastReceiver {
private static final String LAUNCHER_NUMBER = "12345";
#Override
public void onReceive(Context context, Intent intent) {
String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
if (LAUNCHER_NUMBER.equals(phoneNubmer)) {
setResultData(null);
Intent appIntent = new Intent(context, MainActivity.class);
appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(appIntent);
}
}
}
Add it to the manifest:
<receiver android:name=".LaunchViaDialReceiver" >
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
And add the permission to the manifest:
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
The answer to the first part of your question, try this code:
PackageManager pm = getApplicationContext().getPackageManager();
pm.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
Your application will not be visible, but the user can still find it in the Settings >> Applications >> Manage Application
This answer may also be helpful for you.
Please do not forget to post your answer here, if you have already achieved the functionality(pressing some number & opening our application).
Note that the solution:
PackageManager pm = getApplicationContext().getPackageManager();
pm.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
will make the app NOT upgradeable from google play as the OS will not find the package after this component disabling and will not able to re-install it, unless the app is not manullay uninstalled (which is not a user friendly behaviour)
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hideapplication();
}
private void hideapplication() {
// TODO Auto-generated method stub
PackageManager pm = getApplicationContext().getPackageManager();
pm.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}
}
