Menu
I am trying to start an activity defined in another apk, in its AndroidManifest.xml, it defines an activity and with an action, but no category defined.
The format is like
<activity name="...">
<intent-filter>
<action android:name="action name">
<intent-filter>
</activity>
My code is following
Intent i = new Intent("action name");
startActivity(i);
However my apk crashed with uncaught ActivityNotFound exception, the logs read No Activity found to handle intent ... "
Any thoughts?
Thanx a lot.

action : Declares the intent action accepted, in the name attribute. The value must be the literal string value of an action, not the class constant. category: Declares the intent category accepted, in the name attribute. The value must be the literal string value of an action, not the class constant.
public Context call mcontext;<br> // ..... <br> Intent intent = new Intent(call mcontext, AboutActivity. class);<br> call mcontext. startActivity(intent);
If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows: Intent LaunchIntent = getActivity(). getPackageManager(). getLaunchIntentForPackage(CALC_PACKAGE_NAME); startActivity(LaunchIntent);
To start an activity, use the method startActivity(intent) . This method is defined on the Context object which Activity extends. The following code demonstrates how you can start another activity via an intent. # Start the activity connect to the # specified class Intent i = new Intent(this, ActivityTwo.
Looking at the Intent documentation, it says Note also the DEFAULT category supplied here: this is required for the Context.startActivity method to resolve your activity when its component name is not explicitly specified. If the activity's IntentFilter definition does not include that category then you can't start it with startActivity. Try using the setClassName method, and pass it the package class and the activity class you're trying to launch.

you cannot have empty category when you use startActivity(...).
add a default category and this will do the job:
<intent-filter>
<action android:name="action name" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
