I am trying to run a sample bluetooth chat application onto my smartphone (running Android 2.3). The target build project in Eclipse uses Android API level 10
the same project includes this in the manifest:
<uses-sdk minSdkVersion="6" android:targetSdkVersion="10" />
How do I get around this problem? Any Idea
These are my console errors

Check your classpath and project.properties file of your Eclipse project, I thought it was not set properly.
Try this way, using information of these files from a normal project that you have created before. Maybe it could help.

The issue is that you are trying to give access via intents to 3rd party applications that doesn't have permission to access your files.
Android's Security Model doesn't allow any other app to access your private data (assets/resources ....) root here is an exception.
So to make your file available to such apps consider copying your files to a public directory CacheDir maybe the most suitable option.
by doing so you can use intents to view your data the way you are using them right now.
for more about copying files to external dir look here:
Android: how to copy files in assets to sdcard
Also while at it take a look at Android's Security Model
P.S don't forget about WRITE_EXTERNAL_STORAGE permession..
Good luck
You should use text/plain instead of plain/text.
As is mentioned in the exception log,
java.io.FileNotFoundException: /android_asset/USAGE_INSTRUCTIONS_FOR_SMART_RESPONDER.doc: open failed: ENOENT (No such file or directory)
its not able to find the file. Verify if the file is indeed there in that location. Also, as Brigham mentioned, use text/plain.
Exception says that File not exist. Watch that you are pointing to /android_asset/ folder in internal memory.
Are you sure that you not put this file on SDCard?
I wrote a program for android which connects to internet.
I got the following error:
The application has stopped unexpectedly.Please try again..
What's the problem?

Found that my package name is:
com.example.android.networkusage
and on the manifest is as:
android:name="com.example.networkusage.NetworkActivity"
so changed the manifest to:
android:name="com.example.android.networkusage.NetworkActivity"
Looks like your com.example.networkusage.NetworkActivity class is missing.
If it is declared in an external library, add that jar file to the "libs" folder and add it to the build path and then build your project again.
Don't forget to clean it too!
Very short app, you press a button and play a sound bite. The sounds are in mp3/wav format, the app works on the VM in eclipse but does not when trying it on phone (Galaxy S2).
public class SoundBites extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.soundbite);
}
public void SheldonButtonListener(View v){
MediaPlayer mp_bazinga = MediaPlayer.create(getBaseContext(), R.raw.bazinga);
mp_bazinga.start();
}
public void SpanishButtonListener(View v){
MediaPlayer mp_spanish = MediaPlayer.create(getBaseContext(), R.raw.spanish_inquisition);
mp_spanish.start();
}
public void NudgeButtonListener(View v){
MediaPlayer mp_nudge = MediaPlayer.create(getBaseContext(), R.raw.nudge_nudge);
mp_nudge.start();
}
}
with xml-file:

Tried to google this badboy but have come up empty handed so far, anyone got any ideas? The thing that perturbs me is that it works on the VM but not on my phone.
EDIT: Found two problems, one was that I needed to take control over the Audio Volume, the other one seems to be that my WAV-files are corrupt, made it output the mp3 now at least!
According to this question: R.raw.anything cannot be resolved
Eclipse decided to import android.R not your package_name.R file...
Or
You need to use your full package name to reference raw resources.
MediaPlayer mp_nudge = MediaPlayer.create(getBaseContext(), com.exmaple.goran.R.raw.nudge_nudge);
Try Fix Project Properties. Then cleaning your project!
R wil be generated again.
