    <p>I'm trying to get the PID of a process having the class name. The idea is that the user will create a task, select the event, the app and if the app will be opened or killed, so if the user select killed, I want to map the class name in the <code>ComponentName</code> of the intent to the <code>ComponentName</code> in a <code>RunningAppProcessInfo</code>.</p> <p>The problem is that I'm getting a <code>NullPointerException</code>, and I really can't figure out why, it happens when I check the classname in the if - maybe I'm misunderstanding something... Any ideas?</p> <p>Note: I'm passing the context in order to have access to the ActivityManager</p> <pre><code>public static int getPid(Context ctx, Intent intent) { ActivityManager am = (ActivityManager)ctx.getSystemService(Context.ACTIVITY_SERVICE); int pid = 0; for(RunningAppProcessInfo a : am.getRunningAppProcesses()) { //Revisar TODO if(intent.getComponent().getClassName().equals(a.importanceReasonComponent.getClassName())) { pid = a.pid; break; } } return pid; } </code></pre> <p>Here is the logcat:</p> <pre><code>D/su ( 6479): 10106 com.android.test.tasker executing 0 /system/bin/sh using shell /system/bin/sh : sh D/AndroidRuntime( 6446): Shutting down VM W/dalvikvm( 6446): threadid=1: thread exiting with uncaught exception (group=0x40015560) E/AndroidRuntime( 6446): FATAL EXCEPTION: main E/AndroidRuntime( 6446): java.lang.RuntimeException: Error receiving broadcast Intent { act=android.intent.action.AIRPLANE_MODE flg=0x20000000 (has extras) } in com.android.test.tasker.events.AirplaneEvent@4051fee8 E/AndroidRuntime( 6446): at android.app.LoadedApk$ReceiverDispatcher$Args.run(LoadedApk.java:722) E/AndroidRuntime( 6446): at android.os.Handler.handleCallback(Handler.java:587) E/AndroidRuntime( 6446): at android.os.Handler.dispatchMessage(Handler.java:92) E/AndroidRuntime( 6446): at android.os.Looper.loop(Looper.java:130) E/AndroidRuntime( 6446): at android.app.ActivityThread.main(ActivityThread.java:3835) E/AndroidRuntime( 6446): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 6446): at java.lang.reflect.Method.invoke(Method.java:507) E/AndroidRuntime( 6446): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:864) E/AndroidRuntime( 6446): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:622) E/AndroidRuntime( 6446): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 6446): Caused by: java.lang.NullPointerException E/AndroidRuntime( 6446): at com.android.test.tasker.util.Root.getPid(Root.java:97) E/AndroidRuntime( 6446): at com.android.test.tasker.events.GenericalEvent.openKill(GenericalEvent.java:35) E/AndroidRuntime( 6446): at com.android.test.tasker.events.AirplaneEvent.onReceive(AirplaneEvent.java:24) E/AndroidRuntime( 6446): at android.app.LoadedApk$ReceiverDispatcher$Args.run(LoadedApk.java:709) E/AndroidRuntime( 6446): ... 9 more </code></pre>

    1. COWhy don't you debug and see what's null? Off-topic: why don't you pass the ActivityManager right away?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
