Getting read and write permission from External Storage in android

How we get Read and Write Storage permission?

First of all, add following Storage permission in our manifest File.

1 2	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

write following two methods in our activity for the request to granting Read/Write Permission.

public boolean isReadStoragePermissionGranted() {

if (Build.VERSION.SDK_INT >= 23) {

if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)

== PackageManager.PERMISSION_GRANTED) {

Log.v(TAG,"Permission is granted1");

return true;

} else {

Log.v(TAG,"Permission is revoked1");

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 3);

return false;

}

else { //permission is automatically granted on sdk<23 upon installation

Log.v(TAG,"Permission is granted1");

return true;

}

public boolean isWriteStoragePermissionGranted() {

if (Build.VERSION.SDK_INT >= 23) {

if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)

== PackageManager.PERMISSION_GRANTED) {

Log.v(TAG,"Permission is granted2");

return true;

} else {

Log.v(TAG,"Permission is revoked2");

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 2);

return false;

}

else { //permission is automatically granted on sdk<23 upon installation

Log.v(TAG,"Permission is granted2");

return true;

}

Getting permission response in our Activity.

@Override

public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

super.onRequestPermissionsResult(requestCode, permissions, grantResults);

switch (requestCode) {

case 2:

Log.d(TAG, "External storage2");

if(grantResults[0]== PackageManager.PERMISSION_GRANTED){

Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);

//resume tasks needing this permission

downloadPdfFile();

}else{

progress.dismiss();

}

break;

case 3:

Log.d(TAG, "External storage1");

if(grantResults[0]== PackageManager.PERMISSION_GRANTED){

Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);

//resume tasks needing this permission

SharePdfFile();

}else{

progress.dismiss();

}

break;

}
