    <p>I tried to pass values from my main activity to my finish activity but I always got error in my finish activity. I don't know what's wrong with my code.</p> <p>Here's my code from my Level1 class:</p> <p><strong>Note:</strong> the Chronometer is already defined at the top of my activity, before onCreate method.</p> <pre><code>private void showElapsedTime() { chrono.start(); long timeElapsed = SystemClock.elapsedRealtime() - chrono.getBase(); int hours = (int) (timeElapsed / 3600000); int minutes = (int) (timeElapsed - hours * 3600000) / 60000; int seconds = (int) (timeElapsed - hours * 3600000 - minutes * 60000) / 1000; int seco = seconds; Toast.makeText(this, "Elapsed milliseconds: " + seconds, Toast.LENGTH_SHORT).show(); Intent a = new Intent (this, Finish.class); Bundle b = new Bundle(); b.putInt("sec", seco); a.putExtras(b); } </code></pre> <p>and this one is my Finish.class code:</p> <pre><code>Set1 = (TextView) findViewById (R.id.time1); Bundle b = getIntent().getExtras(); Set1.setText("time: " + b.getInt("seco")); </code></pre> <p><strong>LOGCAT:</strong></p> <pre><code>08-20 11:37:49.345: E/AndroidRuntime(815): FATAL EXCEPTION: main 08-20 11:37:49.345: E/AndroidRuntime(815): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.mathattack/com.example.mathattack.Finish}: java.lang.NullPointerException 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread.access$2300(ActivityThread.java:125) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.os.Handler.dispatchMessage(Handler.java:99) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.os.Looper.loop(Looper.java:123) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread.main(ActivityThread.java:4627) 08-20 11:37:49.345: E/AndroidRuntime(815): at java.lang.reflect.Method.invokeNative(Native Method) 08-20 11:37:49.345: E/AndroidRuntime(815): at java.lang.reflect.Method.invoke(Method.java:521) 08-20 11:37:49.345: E/AndroidRuntime(815): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 08-20 11:37:49.345: E/AndroidRuntime(815): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 08-20 11:37:49.345: E/AndroidRuntime(815): at dalvik.system.NativeStart.main(Native Method) 08-20 11:37:49.345: E/AndroidRuntime(815): Caused by: java.lang.NullPointerException 08-20 11:37:49.345: E/AndroidRuntime(815): at com.example.mathattack.Finish.onCreate(Finish.java:33) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 08-20 11:37:49.345: E/AndroidRuntime(815): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) 08-20 11:37:49.345: E/AndroidRuntime(815): ... 11 more </code></pre>

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).
