[android-developers] Re: Android sqlite unable open database problem
you could simplify your code by using openOrCreateDatabase (DATABASE_NAME, Context.MODE_PRIVATE, null); instead. :) Maybe then the problem will resolve itself.

[android-developers] Re: Displaying Virtual Keyboard without expanding EditText
I think this works: InputMethodManager inputMethodManager = (InputMethodManager) getSystemService( Context.INPUT_METHOD_SERVICE ); inputMethodManager.showSoftInput ( yourEditText, InputMethodManager.SHOW_FORCED ); you might have to force the edittext to be focused by running yourEditText.requestFocus() first, Im not sure. cheers, On Jan 28, 11:16 am, swapnil kamble swap.kam...@gmail.com wrote: I want to display keyboard when my app gets started.

[android-developers] Emulator closes when attempting to enter full screen mode

[android-developers] Changing the factory reset-state
I am in a situation where I want to make alot of android-phones fool- proof, so that a company or agency can distribute phones with certain apps installed, and maybe even the apps configured in a certain way. It should be easy to reset the phone to this state, perhaps through the factory reset. Is there any documentation on how to do this? I see this as something very important for Android to be used in these contexts. Relying on the personell to configure and care for the settings of their phone is not an option in this case.

[android-developers] signal when image is rendered?
I have a function that performs two things: First it should set an invisible image to be visible, and then it should read a huge shunk of data from a database. Performing this is easy, but my problem is that android threads this, resulting in a delay of almost a second before the image becomes visible. I have tried extending the images draw- function, and initiating the database-read when draw() is finished, but it seems that when the draw-function finishes the image is not yet visible on the screen.

To summarize: Activities don't have constructors! How do I send data

we can send data from parent activity to childs, using Intent
for example:
In parent activity,
Intent intent = new Intent(this,com.sample.aaa.class); //aaa is
child activity
intent.putExtra(ARG1,value1);
intent.putExtra(ARG2,value2);
StartActivity(intent);
In Child activity (aaa) use Bundle to get the data
public void onCreate(Bundle som) {
super.onCreate(som);
Intent intent = this.getIntent();
Bundle b = intent.getExtras();
String sVal1 = b.getString(ARG1);
String sVal2 = b.getString(ARG2);
...

Hi,
If both activities are in the same application, then just use a global
object and pass that around (singleton or such). Not too tough.
