TabLayout (Android Design Library) Text Color

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Below will reference with our custom style -->
    <item name="android:textAppearance">@style/my_tab_text</item>
</style>

<style name="my_tab_text" parent="Base.TextAppearance.AppCompat">
    <item name="android:textColor">@android:color/holo_blue_dark</item>
</style>

And if you dont want to reference from your Apptheme you can directly specify to TabLayout using Below snippet.

 <android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabTextAppearance="@style/my_tab_text"
            app:tabIndicatorHeight="48dp"/>

if you need zooming effect very close

Custom Kestore to upload signed APK for Playstore using SHA1

Usually when  create the google map it will run proper in locally after setting google key ,package name and SHA1 certificate fingerprint

when upload the APK to play store we have to create custom keystore, then only we will be able to upload playstore
 here when change the keystore default into custom obviously SHA1 fingerprint also will get changed
so we have to try change in eclipse


here or we can try

C:\Users\**********>keytool -list -keystore D:\APK\Keystore\oneapp.keystore
Enter keystore password:

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

oneapp, Jul 19, 2016, PrivateKeyEntry,
Certificate fingerprint (SHA1): CF:64:96:E5:A9:F9:EF:70:6F:7D:18:2B:54:36:E5:7D:
A8:5F:7A:99

There is other way of doing as follow here

Steps (for ADT):

1.Export any project (It will show you an option to create custom keystore).

create your keystore with an extention ".keystore" and give password android and press next.

2.

give alias name = androiddebugkey and password = android

now press finish and your keystore is ready.

1.Go to windows -> preference

and give the path of your custom keystore file

Android application logout after 15 min

Here i just made the code the application should come out when it is not used till 15 minutes

for counting i have taken counter


CountDownTimer timer = new CountDownTimer(15 *60 * 1000, 1000) {

       public void onTick(long millisUntilFinished) {
          //Some code
        Log.d("timer", "--"+millisUntilFinished);
       }

       public void onFinish() {
          //Logout
        finish();
        Log.d("***********", "logout");
       }
    };


then i just calling the timer when it goes to sleep

@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
Log.d("***********", "onPause");
timer.start();
}



meanwhile if the application started again it means like resume, it should cancel

 @Override protected void onResume()
{ Log.d("***********", "onresume");
 super.onResume(); timer.cancel();
 }
