WAV Sound Quality is Poor Android MediaPlayer

Problem:
You have two class with similar names HeadLinesFragment and HeadMyLinesFragment with OnHeadlineSelectedListener.
Check if call correct class in MainActivity.
For example if use HeadMyLinesFragment change implement to HeadMyLinesFragment too!

public class MainActivity extends FragmentActivity 
        implements HeadLinesFragment.OnHeadlineSelectedListener { 
// wrong implements you need correct class name 
//implements  HeadMyLinesFragment.OnHeadlineSelectedListener
//............
HeadMyLinesFragment firstFragment = new HeadMyLinesFragment(); // because in code using HeadMyLinesFragment

Hide module - open dialog: File > Project Structure Ctrl + Alt + Shift + S


Hide module: in opened Dialog select module which will hidden and click on minus (left upper corner)



If module is hidden, you can permanetly delete module from disk. But if you want using module in future,  copy module into other folder (not into AndroidProjects folder and his subbfolders) and delete module permanetly from project and disc. Right mouse click on module and select from menu Delete.


If you want import the backup copy to project, use: File>New>Import mudule

1.) Try delete some apps from Android emulator (can from Eclipse DDMS perspective
- File Explorer tab - data/apps folder path )
2.) Try resize emulator internal storage or SD card storage to hight size
3.)Try add to AndroidManifest.xml android:installLocation="preferExternal"

<manifest xmlns:android="//schemas.android.com/apk/res/android"
    package="com.myweb.mypackage"
    android:installLocation="preferExternal"

4.) Try resize particion from Eclipse
Preferences,
select Android- Launch
Add "-partition-size 1024" into "Default emulator option” field.
Click "Apply” and use your emulator as usual

Check your xml files in Eclipse Graphical Editor and fix problems.



Check project setup, right click on project, select properties, Java build path and
select correct Android version etc.


Right click on project, Android Tools, Fix Project Properties

Menu Eclipse select Project ->Clean.
