I'm trying to call a service from a activity:
When I'm running the program the activity throws an error which says: Not allowed to start service Intent. What am I doing wrong? I'm sorry for possible stupid mistakes in the code, but I'm a newbie.
activity code:
public void startService() {
try {
startService (new Intent ( this , SmsReminderService.class)) ; }
catch (Exception e ) { Log.v("Error" , e.getMessage()) }
}
service code :
public class SmsReminderService extends Service {
#Override
public void onStart(Intent intent, int startid) {
Log.v("SSms", "Service started") ; }}
manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.sms.smsReminder"
android:versionCode="1"
android:versionName="1.0" >

<intent-filter>
<action android:name = "android.intent.category.LAUNCHER" ></action>
</intent-filter>
</service>
</application>
</manifest>
Thanks in advance, Tom
Why this in the service?
<intent-filter>
<action android:name = "android.intent.category.LAUNCHER" ></action>
</intent-filter>
Try to add this:
<uses-permission android:name="android.permission.BIND_REMOTEVIEWS" />

When I create class that extends BrodcastReceiver and register it.

I always register the receiver in the onStart and unregister it in the onStop. I knew this thanks to this answer : https://stackoverflow.com/a/24391706/1203797
If its still not working in your case, simply wrapunregisterReceiver(connectionChangeReceiver); a try-catch block would be the answer, as stated in the link i posted above.
Or you can register it in the manifest, example :
<receiver android:name=".ConnectionChangeReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
I am trying to detect ENTER and EXIT of car mode using UiModeManager. But when I enable/disable "Hands-free mode" in my Samsung S4 BroadcastReceiver not invoked.Here is my code

Any suggestion/fix would help me lot.
Late answer, but try changing
android:exported="false"
to
android:exported="true"
I know there are similar question in statckoverflow, but they just do NOT work for me.
Broadcast receiver(staticly registe via manifest.xml) can NOT receive package_remove event after installing on device (without running main activity)
But the receiver works if main activity is running.
To register broadcastreceiver staticly in AndroidManifest.xml as followings
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.broadcastreceivertesting"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.broadcastreceivertesting.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>
<receiver android:name="com.example.broadcastreceivertesting.PackageBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<data android:scheme="package" />
</intent-filter>
</receiver>
</application>
</manifest>
PackageBroadcastReceiver as a receiver are like following:
public class PackageBroadcastReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
final String action = intent.getAction();
if (Intent.ACTION_PACKAGE_REMOVED.equals(action))
{
File file = new File("/storage/sdcard0/zzz/yyy");
if (file.exists())
{
file.delete();
}
boolean createDir = new File("/storage/sdcard0/zzz/").mkdirs();
Log.d("XXX", "XXXX createDir=" + createDir);
try
{
file.createNewFile();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
}
Do I miss something ?
Try changing this...
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<data android:scheme="package" />
to this...
<intent-filter>
<action android:value="android.intent.action.PACKAGE_REMOVED" />
<scheme android:value="package" />
For more information, see this link on receiving package broadcast intents...

How do i set my application as startup application, so when ever mobile restarts or turned ON, my application starts.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.installedapps22"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<application android:icon="#drawable/cherry_icon" android:label="#string/app_name">
<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>
<activity android:name=".ListInstalledApps" > </activity>
<activity android:name=".TabsLayoutActivity" />
</application>
</manifest>
EDIT Here is my updated code and it is still not working:
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.installedapps22"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:icon="#drawable/cherry_icon" android:label="#string/app_name">
<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>
<receiver android:enabled="true" android:name="com.app.reciever.BootUpReciever">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<activity android:name=".ListInstalledApps" > </activity>
<activity android:name=".TabsLayoutActivity" />
</application>
</manifest>
BroadcastReciever:
package com.example.installedapps22;
public class BootUpReciever extends BroadcastReceiver
{
#Override
public void onReceive(final Context context, Intent intent) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
This is to set the app as the startup application in your device Create a Class extends BroadCast Reciever
public class BootUpReciever extends BroadcastReceiver
{
#Override
public void onReceive(final Context context, Intent intent) {
Intent i = new Intent(context, ServerPreferenceActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
Add permissions to manifest file to access bootup receiver
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Register your receiver which extended the Broadcast receiver in manifest.xml
<receiver android:enabled="true" android:name="com.app.reciever.BootUpReciever">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
first use permission in manifiest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and declare boot receiver in manifiest
<receiver android:name=".BootReciever">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
user receiver to start your mainactivity
public class BootReciever extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}
For your edited code try replacing the following:
android:name="com.app.reciever.BootUpReciever
with:
android:name="com.example.installedapps22.BootUpReciever
I am testing on an physical device (SAMSUNG ACE GT S5830i)
But I am not receiving the BOOT_COMPLETED intent therefore the service is not Receiver is not starting
This is the code I am using.
public class BootCompleteReceiver extends BroadcastReceiver {
static final String TAG = "InfoService.BroadcastReceiver";
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Log.e(TAG, "System boot notification received.");
Intent service = new Intent(context, InfoService.class);
context.startService(service);
} else {
Log.e(TAG, "Intent received: " + intent);
}
}
}
This is the Manifest
<?xml version="1.0" encoding="utf-8"?>
