Question

I’ve making an app and I want to launch a new activity from a menu, but ever time I click the menu button, the app crashes. I’ve tried many ways and all of the have failed.

public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(getApplication())
        .inflate(R.menu.menu, menu);


return(super.onPrepareOptionsMenu(menu));
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
 switch (item.getItemId()) {
   case R.id.Menu1:          
    Toast.makeText(this, "Coming soon", Toast.LENGTH_SHORT).show();
    break;
   case R.id.Menu2:
       Intent Intent = new Intent(this, About.class);
       startActivity(Intent);


 }
return(super.onOptionsItemSelected(item));
}
}

Android Manifest

    <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
  <activity android:name=".AndroidRssReader"
            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=".About" android:label="@string/app_label"></activity>

Answer 1

My implementation of onOptionsItemSelected() is slightly different as I am returning true when I have handled the selection myself, rather than always passing to the superclass.

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.Menu1:
        Intent myIntent = new Intent(this,About.class);
        startActivity(myIntent);
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

Check the documentation

We really need to see the logcat to be sure though
