MonkeyRunner causing Android Settings to Crash

I've been trying to turn on an Accessibility Service using Android's. I run an emulator using Android Studio (Nexus S API 19, armabi-v7). I'm able to open the accessibility settings when the emulator is running. (By clicking on the circled submenu)
Setting Screen with Accessibility Sub-Menu highlighted
Yet when I run try to attach monkeyrunner by opening an interactive monkeyrunner terminal and running:
>> from android.com.monkeyrunner import MonkeyRunner, MonkeyDevice
>> d = MonkeyRunner.waitForConnection()
I'm unable to get navigate to the accessibility settings screen and get the error message
Result of selecting accessibility sub-menu from settings when MonkeyDevice is attached
as soon as I detach the monkeyDevice, I'm able to get to the accessibility settings screen again. Any idea what could cause it?
snippet from the logs when there's an error:

ListView not getting displayed?

I have a activity which uses a listview element as follows
public class List1 extends Activity
{
Context context=this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
try{
//DB
final SQLiteDatabase db;
db = openOrCreateDatabase(
"Secret.db"
, SQLiteDatabase.CREATE_IF_NECESSARY
, null
);
db.setVersion(1);
db.setLocale(Locale.getDefault());
db.setLockingEnabled(true);
Cursor cur = db.query("tbl_user",null,null,null,null,null,null);
//DB Over
ListView listView = (ListView) findViewById(R.id.mylist);
listView.setTextFilterEnabled(true);
final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item,values);
listView.setAdapter(adapter);
listView.setVisibility(0);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
//public void onItemClick(ListView<?> listview, View view, int position,long id)
{
try
{
Intent i=new Intent(List1.this,Form1.class);
i.putExtra("uid","85");
startActivity(i);
finish();
}
catch(Exception e)
{
String insert2="insert into login values("+"\""+e.toString()+"\""+");";
db.execSQL(insert2);
}
}
});
db.close();
//required
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();}
}
}
This is my listview.xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</RelativeLayout>
This is my list_item.xml file which has the required textview
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tv1"
android:padding="10dp"
android:background="#drawable/textview1"
style="#style/textview_text"
android:textSize="16dp">
</TextView>
But the ListView is not working. I mean after coming to this activity the app is showing error showing "APP_NAME is stopped unexpectedly". The same code works for one or two times and then shows the above error continuously after that. May I kno why is it happening?

i think your adapter should know which textViewResourceId it should use.
So try this out: ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item, R.id.tv1,values);

Change this to
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
this
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
And why do you need listView.setVisibility(0)?

final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
Starting from the this spinet of code.
When the db.query returns you should rewind the cursor before starting to use it in the while loop. What if the query returns more the 50 results? Your app will crash with ArrayOutBoundException

Embedding Google MapView crashes android app

model : zt180
firmware : android 2.1-update1-20101030
kernel : 2.6.32.9 usbandroid #1608
build number zt180-eng 2.1-update1 20101030
google maps : 4.5.1
Various crashes occur when embedding the google maps component into an android application. I'm connecting to a router via Wi-Fi for internet access. The stand-alone google maps app seems to work fine. To re-produce, start the maps app and begin scrolling around.
Will fail within a couple of minutes, occasionally on start-up (in setContentView). Most of the errors are when drawing tiles in google code. Sometimes just an Android SEGV.
NOTE : I've tested the same app on the Android developer phone 2 (os 1.6), and it works fine.
My android app is as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="#+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="043yBg1m9IiFNKXIhN5LsdeNndw2k7yrw4Ja3xQ"/>
</RelativeLayout>
import com.google.android.maps.MapActivity;
import android.os.Bundle;
public class Maps extends MapActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Basically, lots of bad things start happening...

The ZT-180 does not have Google Maps, AFAIK.

I fixed it... I kept on trying and, at the end, it turns out that I cannot use an integer-array as the entryValues Source. I just changed that integer-array to a string-array and got it working.
If there's a way to use integer-array as the source for entryValues please comment.

I've been searching for a similar solution to what you are looking for, agreeing that you should be able to use an Integer array to read from and store an integer result.
A solution to this problem I found was at http://kvance.livejournal.com/1039349.html, which I found to be useful.
It doesn't quite solve the problem the way I was thinking or that way I think you want it to, instead you still specify your initial / selection values with a String array although when the ListPreference saves it back to the SharedPreferences it saves as an Integer instead of a String (doing the conversion when the user selects it), removing the need to have to convert it possibly many times throughout your application when accessing the preference value.
