    <p>Hi I'm this is a reask of a previous question just because i wasn't clear before. i have a json feed that consists which i found the length of the array in it. as it should it produces one. but what i'm trying to do is if a second item were to be added that feed another layout would need to be used.</p> <p>so i currently have a string that contains the String value of YES this is then sent in an intent to anther activity this is placed inside an if statement that says if x = Yes then use layout1 if x = no use layout2. </p> <p>the problem i'm having is when i put a string in the if statement and log it it works but when i put setContentView in and it forces the app to close why?</p> <p>here is my code</p> <p>in the 1st activity</p> <pre><code>HttpResponse response = client.execute(post); BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8")); String json = reader.readLine(); JSONObject obj = new JSONObject(json); JSONObject objData = obj.getJSONObject("data"); JSONArray jArray = objData.getJSONArray("structure"); leagueCount = jArray.length(); if (leagueCount == 1){ teamFeedStructure = "YES" ; } if (leagueCount == 2){ teamFeedStructure = "NO" ; } </code></pre> <p>now the intent sent</p> <pre><code>Intent mainIntent = new Intent(firstActivity.this,secondActivity.class); mainIntent.putExtra("leagueCount", teamFeedStructure); firstActivity.this.startActivity(mainIntent); firstActivity.this.finish(); </code></pre> <p>now in the second Activity</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); //setContentView(R.layout.introact); String leagueCount = getIntent().getExtras().getString("leagueCount"); //String leaguecount = String.valueOf(leagueCount); Log.v("lc", leagueCount); if (leagueCount == "YES"){ String one = "one"; setContentView(R.layout.introact); Log.v("lc", one); } //if (leaguecount == "2"){ //setContentView(R.layout.introact); //} </code></pre> <p>The Error</p> <pre><code>04-23 21:53:34.455: W/dalvikvm(954): threadid=1: thread exiting with uncaught exception (group=0x40015560) 04-23 21:53:34.465: E/AndroidRuntime(954): FATAL EXCEPTION: main 04-23 21:53:34.465: E/AndroidRuntime(954): java.lang.RuntimeException: Unable to start activity ComponentInfo{co.uk.fantasticmedia.TheEvoStikLeague/co.uk.fantasticmedia.TheEvoStikLeague.IntroActivity}: java.lang.NullPointerException 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1647) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.os.Handler.dispatchMessage(Handler.java:99) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.os.Looper.loop(Looper.java:130) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread.main(ActivityThread.java:3683) 04-23 21:53:34.465: E/AndroidRuntime(954): at java.lang.reflect.Method.invokeNative(Native Method) 04-23 21:53:34.465: E/AndroidRuntime(954): at java.lang.reflect.Method.invoke(Method.java:507) 04-23 21:53:34.465: E/AndroidRuntime(954): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 04-23 21:53:34.465: E/AndroidRuntime(954): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 04-23 21:53:34.465: E/AndroidRuntime(954): at dalvik.system.NativeStart.main(Native Method) 04-23 21:53:34.465: E/AndroidRuntime(954): Caused by: java.lang.NullPointerException 04-23 21:53:34.465: E/AndroidRuntime(954): at co.uk.fantasticmedia.TheEvoStikLeague.IntroActivity.onCreate(IntroActivity.java:45) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 04-23 21:53:34.465: E/AndroidRuntime(954): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) 04-23 21:53:34.465: E/AndroidRuntime(954): ... 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).
