Try convert WAV file to MP3 format for example by Audacity sound editor and replay:
//audacity.sourceforge.net/help/faq_i18n?s=install&i=lame-mp3
//audacity.sourceforge.net/help/faq_i18n?s=install&i=lame-mp3
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.mymp3file);
mp.setLooping(true);
mp.start();
If you using Context as parameter of function try this solution:
public class MyActivity extends Activity {
// bla bla bla .......
//error
myFc( getapplicationcontext());
// OK
myFc(MyActivity.this);
Put your sglite database to Android Eclipse project folder named Assets.
On device will copy database file to application folder as this example:
On device will copy database file to application folder as this example:
public void createDatabase(Context myContext) throws IOException {
String sPackName = myContext.getPackageName();
InputStream assetsDB = myContext.getAssets().open("myDatabase");
OutputStream dbOut = new FileOutputStream("/data/data/"+sPackName+"/database");
byte[] buffer = new byte[1024];
int length;
while ((length = assetsDB.read(buffer))>0){
dbOut.write(buffer, 0, length);
}
dbOut.flush();
dbOut.close();
assetsDB.close();
}
If you often copy your Android project to another you have to using function for obtaining varied information about package.
This code show how get package name in Android application as string:
This code show how get package name in Android application as string:
Context context = getContext(); // this.getContext(); getApplicationContext(); etc.
String sPackName = context.getPackageName();
