How to create directory in android framework?

Question

I want to create my directory in android framework. For example, "/stoage/myTestDir/"

So, i try to add this code in "Kitkat/frameworks/base/services/java/com/android/server/BootReceiver.java".

BootReceiver.java

@Overrinde
public void onReceive(final Context context, Intent intent){
    /*...*/

    if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED")){

    File testDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/myTestDir");

    if(!testDir.exists(){
        if(testDir.mkdirs()==true){
            Log.i("mkdirs() success", "mkdirs() success");
        else{
            Log.i("mkdirs() fail", "mkdirs() fail");
        }
    }

    /*...*/
}

After framework building, log shows "mkdirs() fail".

So why cannot fail to create dir in android framework with my code?

thanks.

Log's argument tag should not be that way."Log.i("BootReceiver","XXX")". — T-Chen, Aug 12 '15 at 07:54

add permissions WRITE_EXTERNAL_STORAGE in your manifest file (http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE)

I already added permissions in "Kitkat/frameworks/base/core/res/AndroidMenifest.xml". But, results are same. :( – Un-Su Kim Aug 12 '15 at 08:13
may be name of file and name of dir must be different – mlevytskiy Aug 12 '15 at 08:16
try new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/myTestDir/") – mlevytskiy Aug 12 '15 at 08:17
i try File testDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/myTestDir/"); But, mkdirs() failed too. – Un-Su Kim Aug 12 '15 at 08:56
