Google Android example source code - is text changed in EditText ?
EditText hEditText;
// TextChanged in onCreate
hEditText = (EditText)findViewById(R.id.idEditText);
hEditText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable str) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence sq, int start, int before,
int count) {
}
});If Android emulator freezes at startup, try create new virtual device with smaller memory and cpu usage, or select older version of Android, or buy new pc with higher performance.
- open AVD MANAGER
- press Create Virtual Device
- select Device with small memory usage (e.g. 480x800 of resolution) - Next
- check - Show downloadable ....
- Download - lower version of system Android, select, press - Next
- check data, Show Advanced Settings, check Use host... and press Finish

Density independent pixel (dp)
Dots per inch (dpi) .. physical pixels per inch
px = dp * (dpi / 160)
public static int dpToPx(int dp)
{
return (int) (dp * Resources.getSystem().getDisplayMetrics().density);
}
public static int pxToDp(int px)
{
return (int) (px / Resources.getSystem().getDisplayMetrics().density);
}
Throws multiple exceptions Java example source code
public void callFc()
throws IndexOutOfBoundsException, ArithmeticException
{
// my code for example:
String[] sArray = {"aa","bb"};
String str = sArray[5]; // IndexOutOfBoundsException
int n = 5 / 0; // ArithmeticException
}
public void someFC (){
try{
callFc();
}
catch(IndexOutOfBoundsException e){
Log.e("TAG", e.toString());
}
catch(ArithmeticException e2){
Log.e2("TAG",e2.toString());
}
}
public boolean isConnected() {
try {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo().isConnectedOrConnecting();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.e("isConnected", e.getMessage());
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
return false;
}
