When I run my android UIAutomator code, it shows following error.
INSTRUMENTATION_RESULT: shortMsg=java.lang.RuntimeException
INSTRUMENTATION_RESULT: longMsg=com.android.ui.testing
INSTRUMENTATION_CODE: 0
I just ran the sample code given in developer.android.com
How to solve this error?

If you get a ClassNotFindException while running your uiautomator tests :
Some of us my get this error because their ROM puts the folder /data/dalvik-cache in read-only mode. That happened to me with Cyanogen for a S3.
In that case type, in bash :
adb shell
su
chmod 777 /data/dalvik-cache
exit
rerun your tests and that should work. As dalvik-cache is locked for apps, uiautomator can't ask dalvik to unzip the jar of your tests and dalvik won't find the its classes.
See if removing the #UiThreadTest annotation or removing the runOnUiThread() call or re-factoring your tests work. But without a logcat, difficult to understand where it's coming from.
Had the same problem. Most demos I've seen indicate to install the jar to /data/local/tmp/. I've seen others indicate to try and install it to your sd card (/storage/sdcard0). After doing that it worked. Seems to be a problem with read permissions.
I solved this error by using"ant build" to create my jar.If u use export in eclipse to create a jar file, there might be some errors in the resulting class file, hence the above class not found error.

I have made made 2 xml files that have identical widgets. First file (main) the widgets are arranged in a Relative layout and the second (testgrid2) the widgets are in a TableLayout. The first xml file works fine and app runs. The second xml file I created so I can test before I replace it with the original (main). when I test the second (testgrids)it crashes but I cannot understand the log cat errors it is generating.
The only changes I make to test is in the set Content view.
setContentView(R.layout.main);
and testing
setContentView(R.layout.testgrid2);

I downloaded a library called Android Maps Extensions from Github.
I can run the demo of this library in debugging mode, on my Samsung Note (GT-N7000) which runs Android 4.0.4.
If I click a button inside app, the app will stop and the screen will become black and after several seconds, and a dialog appears saying:
Unfortunately, Android Maps Extensions has stopped.
I am not sure what is happening. The logcat output can be seen below:

I coded a Dialog that shows up with 2 textviews and 2 buttons.
I googled for that Problem as well but I didn't find anything that mathced my issue.
Here is some Code:
case R.id.open:
openDialog=new Dialog(this);
openDialog.setContentView(R.layout.open_dialog);
openDialog.setTitle(head);
openDialog.setCancelable(true);
Button open_cancel=(Button)findViewById(R.id.open_cancel);
open_cancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
openDialog.cancel();
}
});
but I can't show the dialog up with the buttons.
If I call it without these Lines there is no Problem:
Button open_cancel=(Button)findViewById(R.id.open_cancel);
open_cancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
openDialog.cancel();
}
});
This is the XML File:

android:layout_height="wrap_content"
android:text="cancel"
/>
</LinearLayout>

Try this,
Button open_cancel=(Button)openDialog.findViewById(R.id.open_cancel);
Does anyone know how to create a button which will help me to switch between tabs?
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {{
// Perform action on click
if (v.getId() == R.id.button1) {
setContentView(R.layout.tab3);
}
else if (v.getId() == R.id.button1) {
setContentView(R.layout.main);
}
}
}
});
}}
this is the code in my tab 1, this next code is the button in my tab.xml. i want to press the buy button below and i want it to go to another tab, is this possible?
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/imageButton1"
android:text="Buy"
android:onClick="tab3" />
this is my logcat file

+1 Midoalageb and +1 Mark Gjol have given you exactly what you need to switch the tab. What they are leaving out is the code for the event you are trying to do. What you need to do is set up a button on TAB1 that will have an onClick() listener that will call either getTabHost().setCurrentTabByTag(TAB2); or getTabHost().setCurrentTab(1);. Either one of those will work fine, just depends on how you want to do it.
Do you know how to do buttons and onClick() listeners? If not, google has some great examples. Just create a button in your tabView then set the onClick and then put your code in there for switching to the tab you want.
Another post that is very similar to this one that may help you out.
getTabHost().setCurrentTabByTag(TAB2);
This will look for the tab labeled "TAB2" and change to that tab.
getTabHost().setCurrentTab(1);
This will look for the tab with the index of "1" and change to that tab.
In regards to your xml
The xml files are mainly used to abstract defining your Views from the implementation of your Views. This allows you or other developers to provide different views to your code if needed. It helps provide a way to use the MVC pattern. However, this pattern is a little different in Android, but the xml file is most commonly considered the View in that pattern.
So Yes, if you are going to have multiple buttons they will need to be defined in your xml and implemented in your code.
In regards to your button dilema
The API for Button from google actually provides you with an example of this on the very front page. Keep in mind that Android is maturing very fast as a development platform and A LOT of this stuff is actually well documented already on line. The API documentation is also very good and gives great examples. Go by there and read it and you will most likely solve a lot of the more easy problems there.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textview = new TextView(this);
textview.setText("This is Tab1");
setContentView(textview);
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
// perform the switch to tab event here for instance...
getTabHost().setCurrentTabByTag("TAB2");
}
});
}
When you create your tabs you give them a tag, let's store one such tag in the variable TAB_1. So in your onClick() method, you select that tab by:
getTabHost().setCurrentTabByTag(TAB_1);
Or, as midoalageb wrote, by index:
getTabHost().setCurrentTab(index);
Here is an explanation of Tab example :
Create a master Activity:
public class HelloTabWidget extends TabActivity
And create an Activity for each Tab:
public class ArtistsActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textview = new TextView(this);
textview.setText("This is the Artists tab");
setContentView(textview); // you replace this with your layout for each view
}
}
In the master Activity (HelloTabWidget), initiate a TabHost:
TabHost tabHost = getTabHost();
And add TabSpecs for each Tab you have:
intent = new Intent().setClass(this, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
Select which Tab you need to be the default one:
tabHost.setCurrentTab(int index);
And finally your Button's onClickListener should be set in the Activity of the Tab containing the Button to:
intent = new Intent().setClass(this, ArtistsActivity.class);
startActivity(intent);
This Button should be present in all Tabs if you want it to switch between them.
