  1. POForce close on Intent null return
    text
    copied!<p>Hola! This is my first post. I'm having trouble with the code snippet below.</p> <p>Basically, you click an EditText and you're presented with a file browser. If you choose a file all is right with the world. If you choose the back/return button on your phone without choosing a file a force close is caused. I think this is because I'm returning a null from the intent, but I do not know how to fix nor what I should try/ catch.</p> <p>Your help is greatly appreciated.</p> <p>Code:</p> <pre><code> filename = (EditText) findViewById(R.id.selectFile); filename.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent intent = new Intent(); intent.addCategory(Intent.CATEGORY_OPENABLE); intent.setType("text/csv"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent,"Select File"),1); } }); </code></pre> <p>The result from LogCat.</p> <p>02-15 10:03:27.224: DEBUG/dalvikvm(133): GC_EXPLICIT freed 74K, 52% free 2860K/5895K, external 2101K/2456K, paused 69ms 02-15 10:03:30.314: INFO/ActivityManager(61): Starting: Intent { cmp=com.aydabtu.BroadcastSMS/.DataManagerActivity } from pid 557 02-15 10:03:30.483: DEBUG/dalvikvm(557): GC_EXTERNAL_ALLOC freed 228K, 52% free 2656K/5511K, external 1465K/1828K, paused 63ms 02-15 10:03:30.633: WARN/AdMobSDK(557): Ignoring requestFreshAd() because we are requesting an ad right now already. 02-15 10:03:30.643: INFO/AdMobSDK(557): Location information is not being used for ad requests.
