I have this very unpeculiar exception.The thing is have i have this app that has a button to start
InputMethodService
that starts like this
public class MyGroovyIme extends InputMethodService {
and this is how it looks in manifest.
<service
android:name=".MyGroovyIme"
android:enabled="true"
android:exported="true"
android:permission="android.permission.BIND_INPUT_METHOD" >
<intent-filter>
<action android:name="android.view.InputMethod" />
<!-- <category android:name="android.intent.category.DEFAULT" /> -->
</intent-filter>
<meta-data
android:name="android.view.im"
android:resource="@xml/method" />
</service>
and this is how I start service
void startServer() {
Log.v(TAG, "Starting service...");
Intent serviceIntent = new Intent(this, MyGroovyIme.class);
startService(serviceIntent);
Log.v(TAG, "Starting service...success!!!");
// this.finish();
Log.v(TAG, "finish called...");
}
the whole setup works like a charm when i do it on Tablet(Moto XOOM ,its 3.2) but when I do it on Devices that run on 2.2 and 2.1(i havent tried it on 2.3 and cant use emulator either) this is what i get

I do understand the security concerns but shouldnt it be same for all devices or am i missing something specific to versions <3.2
After a long search have not found a reliable answer and still have not got the exact reason.. but going through the new features have found hardware features that were added at later versions may have led to this leniency in Android OS. Here is the link describing major updates for Android here
