POAndroid context issues from imported package
text
Body
copied!<p>I have a twitter package that runs fine on its own. Now when I import it and try to use it in my main app I hit upon issues of nullpointerexceptions. The first I solved, but immediately ran into another. I now believe it is because I am handling the context incorrectly.</p> <p>Here is how I have called one method from my included package.</p> <pre><code> TweetToTwitterActivity twitter = new TweetToTwitterActivity(); twitter.buttonLogin(v, context); </code></pre> <p>Now in the TweetToTwitterActivity file I have this. The first method runs fine but I am now getting a null pointer exception from this line. I think I am going about this completely the wrong way. Can anyone help me understand how to run methods properly from an imported class?</p> <blockquote> <p>setContentView(twitterSite);</p> </blockquote> <pre><code>public void buttonLogin(View v, Context context) { mPrefs = context.getSharedPreferences("twitterPrefs", MODE_PRIVATE); // Load the twitter4j helper mTwitter = new TwitterFactory().getInstance(); // Tell twitter4j that we want to use it with our app mTwitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET); if (mPrefs.contains(PREF_ACCESS_TOKEN)) { Log.i(TAG, "Repeat User"); loginAuthorisedUser(); } else { Log.i(TAG, "New User"); loginNewUser(context); } } private void loginNewUser(Context context) { try { Log.i(TAG, "Request App Authentication"); mReqToken = mTwitter.getOAuthRequestToken(CALLBACK_URL); Log.i(TAG, "Starting Webview to login to twitter"); WebView twitterSite = new WebView(context); twitterSite.requestFocus(View.FOCUS_DOWN); twitterSite.setOnTouchListener(new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_UP: if (!v.hasFocus()) { v.requestFocus(); } break; } return false; } }); twitterSite.loadUrl(mReqToken.getAuthenticationURL()); setContentView(twitterSite); } catch (TwitterException e) { Log.e("HelloWorld", "Error in activity", e); Toast.makeText(this, "Twitter Login error, try again later", Toast.LENGTH_SHORT).show(); } } </code></pre>
