    copied!<p>All of the code below works just as desired. That is, until I attempt to add a second onClickListener to another image. The code I am trying to add, and where I am trying to add it is listed as comments in the code below. Does anyone see anything that I'm missing here? I feel as though there shouldn't be any problems with this extra implementation.</p> <p>public class MainActivity extends Activity {</p> <pre><code>ImageView mImage; //ImageView journal; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mImage = (ImageView)MainActivity.this.findViewById(R.id.Floaterimg); //journal = (ImageView)MainActivity.this.findViewById(R.id.journbtn); //journal.setOnClickListener(new View.OnClickListener() { //@Override //public void onClick (View v) { //Intent i = new Intent(MainActivity.this, //SecondActivity.class); //startActivity(i); //} //}); final Handler randomizer = new Handler(); final Runnable rrandomizer = new Runnable() { public void run() { RelativeLayout.LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); params.topMargin = (int)(Math.random()*2000 + 1); params.leftMargin = (int)(Math.random()*3000 + 1); mImage.setLayoutParams(params); randomizer.postDelayed(this, 5000); } }; rrandomizer.run(); mImage.setOnClickListener(new View.OnClickListener() { int numClicks = 0; @Override public void onClick(View arg0) { numClicks++; if(numClicks &gt; 5) { Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos); byte[] b = baos.toByteArray(); Intent intent = new Intent(MainActivity.this, SecondActivity.class); intent.putExtra("picture", b); } } }); } </code></pre> <p>};</p> <p>Edit:</p> <p>Errors from the logcat after pressing the button:</p> <pre><code>10-18 14:17:32.529: E/InputDispatcher(17677): Event_report_payload: Failed to write keypress event to kernel, error = 5 10-18 14:17:32.529: E/dhcpcd(7483): open_udp_socket: No such device 10-18 14:17:32.549: E/dhcpcd(7483): open_socket: No such file or directory 10-18 14:17:32.549: E/dhcpcd(7483): send_raw_packet: No such file or directory 10-18 14:17:32.609: E/InputDispatcher(17677): Event_report_payload: Failed to write keypress event to kernel, error = 5 10-18 14:17:32.759: E/AndroidRuntime(26780): Uncaught handler: thread main exiting due to uncaught exception 10-18 14:17:32.759: E/Monkey(26780): exception :java.io.FileNotFoundException: /dev/kmsg (Permission denied) 10-18 14:17:32.809: E/AndroidRuntime(26780): exception :java.io.FileNotFoundException: /dev/kmsg (Permission denied) 10-18 14:17:32.809: E/AndroidRuntime(26780): FATAL EXCEPTION: main 10-18 14:17:32.809: E/AndroidRuntime(26780): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.test/com.example.test.SecondActivity}: java.lang.NullPointerException 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1664) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1680) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:945) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.os.Handler.dispatchMessage(Handler.java:99) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.os.Looper.loop(Looper.java:130) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread.main(ActivityThread.java:3719) 10-18 14:17:32.809: E/AndroidRuntime(26780): at java.lang.reflect.Method.invokeNative(Native Method) 10-18 14:17:32.809: E/AndroidRuntime(26780): at java.lang.reflect.Method.invoke(Method.java:507) 10-18 14:17:32.809: E/AndroidRuntime(26780): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:895) 10-18 14:17:32.809: E/AndroidRuntime(26780): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:653) 10-18 14:17:32.809: E/AndroidRuntime(26780): at dalvik.system.NativeStart.main(Native Method) 10-18 14:17:32.809: E/AndroidRuntime(26780): Caused by: java.lang.NullPointerException 10-18 14:17:32.809: E/AndroidRuntime(26780): at com.example.inkuesttest.SecondActivity.onCreate(SecondActivity.java:18) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 10-18 14:17:32.809: E/AndroidRuntime(26780): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1628) 10-18 14:17:32.809: E/AndroidRuntime(26780): ... 11 more 10-18 14:17:32.829: E/AndroidRuntime(26780): exception :java.io.FileNotFoundException: /dev/kmsg (Permission denied) 10-18 14:17:32.869: E/ActivityManager(17677): set systemprop back to original value~ </code></pre> <p>Edit:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
