But when i change AccelerometerManager activity to a service, it doesn't work and i got an error.</p> <pre><code>//this is the activity that i want change public class Accelerometer extends Activity implements AccelerometerListener { private static Context CONTEXT; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); CONTEXT = this; } protected void onResume() { super.onResume(); if (AccelerometerManager.isSupported()) { AccelerometerManager.startListening(this); } } protected void onDestroy() { super.onDestroy(); if (AccelerometerManager.isListening()) { AccelerometerManager.stopListening(); } } public static Context getContext() { return CONTEXT; } /** * onShake callback */ public void onShake(float force) { Toast.makeText(this, "Phone shaked : " + force, 1000).show(); } /** * onAccelerationChanged callback */ public void onAccelerationChanged(float x, float y, float z) { ((TextView) findViewById(R.id.x)).setText(String.valueOf(x)); ((TextView) findViewById(R.id.y)).setText(String.valueOf(y)); ((TextView) findViewById(R.id.z)).setText(String.valueOf(z)); } } </code></pre> <p>//this is my service when i change it, my error is hir public </p> <pre><code>class Accelerometer extends Service implements AccelerometerListener{ private static Context CONTEXT; @Override public IBinder onBind(Intent intent) { // TODO Put your code here return null; } @Override public void onCreate() { System.out.println(”start listening”); // if (AccelerometerManager.isSupported()) { AccelerometerManager.startListening(this); // } } @Override public void onDestroy() { System.out.println(”start listening”); // if (AccelerometerManager.isListening()) { AccelerometerManager.stopListening(); // } } public static Context getContext() { return CONTEXT; } /** * onShake callback */ public void onShake(float force) { Toast.makeText(this, “Phone shaked niktilha omha ya 3ammi el7ag: ” + force, 1000).show(); } /** * onAccelerationChanged callback */ public void onAccelerationChanged(float x, float y, float z) { System.out.println(”x = “+x+” y = “+y+” z = “+z); } } </code></pre> <p>Thanks for help.</p>

    1. COis it a nullpointerexception? You don't seem to be initializing the variable CONTEXT, and if you call the static method getContext() from somewhere that would certainly cause an error. It would help a lot if you post the logcat output so we can see which error you get.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
