程式如下
Intent intent_music = new Intent();
intent_music = getPackageManager().getLaunchIntentForPackage("com.android.music");
startActivity(intent_music);

發生應用程式異常終止:
資訊如下:
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.music/com.android.internal.app.ResolverActivity}; have you declared this activity in your AndroidManifest.xml?
at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1405)
at android.app.Instrumentation.execStartActivity(Instrumentation.java:1379)
at android.app.Activity.startActivityForResult(Activity.java:2827)
at android.app.Activity.startActivity(Activity.java:2933)
at com.nexes.list.ProcessManager$1.onClick(ProcessManager.java:117)
at com.android.internal.app.AlertController$AlertParams$3.onItemClick(AlertController.java:873)
....
請問該如何解決?
