I use android 1.5. I did not put specific entry in the manifest.
Anyone have an idea or an other method for call my market page?
Expanding on a previous comment, you can check if the Intent can be resolved on the device before starting a new Activity with it using code like this:
PackageManager pm = context.getPackageManager();
ComponentName cn = intent.resolveActivity(pm);
if (cn != null) {
this.startActivity(intent);
}
Try adding the following flat to your intent.
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
If you're running this code on the emulator, you should know that there is no Android Market application on the emulator, so it will throw you this exception. There should be no problem on most of the real devices. Hope this helps.

I have a game in Google Play. It have been working fine in the previous 3 updates. But in the 4th after you download and install the update the game crashes only in Android 4.1.1 devices.
It happens because somehow GooglePlay installed incorrectly the application and the native library is not correctly set up.
Reading some Google forms I believe this is know problem of that android firmware. I already worked around that by saving the native library in the res files and coping it to /data/data/com.minix.android.Game/files and loading it from there. Yet the players lost all of their progress, like if the corrupt installation clears the game data.

Several reasons that might cause this:
You don't have this in your code:
static {
System.loadLibrary("mylibraryname");
}
You changed your package name in the code or in the package itself and they don't match.
You use an expired or invalid signature to sign your app.
I'm trying to use some emulators to run my apps for debugging. This app runs perfectly on my phone, but when I load it up into the emulator it crashes whenever I invoke an opencv function. The emulator is using the intel atom x86 cpu. Do I have to run them with the arm7?

I would really like some help. I am a noob so if there is more info you need about this problem to help me feel free to ask.
Most likely some users don't have a native video player in their phone.
Weird, but possible.
Yes. Your users with the errors probably don't have a video player installed than can handle a URL with the file type of video/flv.
I have this code:
String sql="UPDATE LAST_OPEN SET LAST_OPEN="+DATE+" WHERE STUDENT_ID ="+STUDENT_ID+" AND ITEM_ID="+ITEM_ID+" AND ITEM_NAME="+ITEM_TYPE+";";
db.execSQL(sql);
Where LAST_OPEN field is timestamp.I tried to run the same query in SQlite Browser it was working fine.But when this Sql is executed in app it shows this:

Can anyone tell where I am getting wrong?
Try with this sql statement :
String sql="UPDATE LAST_OPEN SET LAST_OPEN='"+DATE+"' WHERE STUDENT_ID ="+STUDENT_ID+" AND ITEM_ID="+ITEM_ID+" AND ITEM_NAME="+ITEM_TYPE+";";
as I know, when you are using any string data in sql statement you need to add '' in the beginning of the variable and at the end of it.
Try to change
LAST_OPEN=2012-02-13 13:12:39
with
LAST_OPEN = "2012-02-13 13:12:39"
The space between the numbers can be the problem. Hope this helps.
I'm passing an object from activity to another. Then from that activity to another one.
When I try to access an attribute of the passed object from the 3rd activity, i get a null pointer exception.
I've set the attribute also. So i don't understand the reason for it.
Code from the first activity:
private Task t;
public void onClick(View v) {
if(v == this.btnAdd){
this.addItem(this.txtTask.getText().toString());
this.addTask(this.txtTask.getText().toString());
}
}
private void addTask(String taskName){
if(taskName.length()>0){
t = new Task(taskName);
this.tasks.add(t);
}
}
public void onItemClick(AdapterView<?> parent, View view, int position,
long id3) {
Intent myIntent = new Intent(getApplicationContext(), TabSwitch.class);
myIntent.putExtra("taskItem", t);
startActivity(myIntent);
}
});
From the second activity:
private TextView selectedTask;
Intent i=getIntent();
Task taskItem = (Task) i.getSerializableExtra("taskItem");
i = new Intent().setClass(this, Info.class);
i.putExtra("taskItem", taskItem);
From the 3rd activity:
Intent i=getIntent();
Task task =(Task) i.getSerializableExtra("taskItem");
selectedTask.setText(task.getTaskName());
Here is the log:

Does your Activity maintain its life cycle properly? Looks like not. If you leave, say, activity A in favor of activity B (so the stack of activities is A > B), then once activity A becomes invisible the OS may decide to kill it (there are hacks to prevent it, but those are hacks, so you better avoid them). So when you come back to the activity A from B, the OS will restore the activity A for you (however it's you who is responsible for proper activity state maintaining - the Activity API has special callbacks for that - persist/restore your tasks at those points). Here is the official tutorial on this: Managing the Activity Lifecycle.
Is the null pointer exception being thrown because the object t is null?! Looks that way. Make sure you're creating t somewhere.
If all these activities are under the same Application, I would recommend you simply extend the Application class with your own custom application class that stores this object that is persistent through out the application (unless it is interrupted and then closed, read Arhimed's comment below). This is a much more robust solution as it is resilient to activity life cycles.
Here is a link that should help with implementing this:
