[android-beginners] startActivity crash
Hello.
I have an application in which I am trying to start an activity (geotest)
in, and the activity crashes upon start of the application. Below is my
code and my logcat output. I can't figure out the problem, because I have
several other activities I am able to start exactly the same way with no
problem. When I compare the code, I can't see what I'm doing wrong with the
activity that crashes. Am I missing permissions for something maybe? Can
someone please help? Thanks!

Button geotagbtn = null;
Button next2btn = null;
@Override

super.onCreate(savedInstanceState);
geotagbtn = (Button) findViewById(R.id.geotagbtn);
geotagbtn.setOnClickListener(new View.OnClickListener() {

//startActivity(new Intent(MainMenu.this, TakePic.class));
Toast.makeText(geotest.this, Geotag Picture coming soon, 5000).show();
}
});

next2btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//startActivity(new Intent(Geotest.this, FieldGuide.class));
Toast.makeText(geotest.this, Next coming soon, 5000).show();

[android-beginners] startActivity() crash...
Here is the code that I am using to bring a running activity
to the foreground:
ActivityManager.RunningTaskInfo task = getTask(idx);
if (task != null)
{
Intent intent = new Intent();
intent.setClassName(task.topActivity.getPackageName(),
task.topActivity.getClassName());
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try
{
m_context.startActivity(intent);
}
catch (ActivityNotFoundException e)
{
Toast.makeText(m_context, Unable to launch
activity..., Toast.LENGTH_SHORT).show();
}
}
- Crash Scenario 1:
Switching to any task in the list of running task that has started
another activity (i.e. task.topActivity and task.baseActivity are
different) causes a crash. I have tried the code above using both
task.topActivity and task.baseActivity but the results are the same...
force close.
- Crash Scenario 2:
Switching to specific tasks always causes a force close. For example,
when I try to switch to the Calendar Task when it is running my
program always crashes. However, I can successfully switch to Google
Maps, Home, Browser, and most others.
I have been unable to find any information about these issue anywhere
in google groups or on the internet...
