I am a newbie in android developement. I am just making a simple project to save the font size of the text entered everytime seekbar moves.
I completed the project with no errors but when I run the application it shows error message in Emulator says "Unfortunately SharedPreferences has been Stopped".
I have searched in below links as well for this and applied all but there was no such error in my case:
- Unfortunately app has stopped in Android Emulator
- Unfortunately HelloListView has stopped
- Unfortunately, *name of app* has stopped
- Unfortunately, MyApp has Stopped In Emulator
- unfortunately app has stopped in emulator
- unfortunately the application has stoped
- Unfortunately Project_Name Has Stopped
- "Unfortunately, app name has stopped." android device or emulator
and few more.
Here's project's LAYOUT file is (sharedprefer.xml):
<Seekbar android:id="@+id/sb"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<EditText android:id="@+id/et"
android:hint="@string/txt"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<Button
android:id="@+id/b"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/s" />
.Java file is (Main.java) :
import android.app.Activity; import android.content.SharedPreferences; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; import android.widget.Toast;
public class Main extends Activity {
private SharedPreferences pref;
private String pName = "MyPref";
private EditText et;
private SeekBar sb;
private Button b;
private static final String FONT_SIZE_KEY = "fontsize";
private final static String TEXT_VALUE_KEY = "textvalue";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sharedprefer);
et = (EditText) findViewById(R.id.et);
sb = (SeekBar) findViewById(R.id.sb);
b = (Button) findViewById(R.id.b);
b.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
pref = getSharedPreferences(pName, MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putFloat(FONT_SIZE_KEY, et.getTextSize());
editor.putString(TEXT_VALUE_KEY, et.getText().toString());
editor.commit();
Toast.makeText(getBaseContext(), "Saved" , Toast.LENGTH_LONG).show();
}
});
pref = getSharedPreferences(pName, MODE_PRIVATE);
float fontsize = pref.getFloat(FONT_SIZE_KEY, 14);
sb.setProgress((int)fontsize);
et.setText(pref.getString(TEXT_VALUE_KEY, ""));
et.setTextSize(sb.getProgress());
sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){
@Override
public void onProgressChanged(SeekBar sbar, int progress, boolean fromUser) {
// TODO Auto-generated method stub
et.setTextSize(progress);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
and I found errors in LOGCAT are :
