Some phones need permission READ_CONTACTS to read from contact picker
android, java, permissions
Solution
HTC ONE does not need: `<uses-permission android:name="android.permission.READ_CONTACTS" />` on HTC EVO 3D however, following code throws an exception
If the `Uri` you are getting is coming from `ACTION_PICK` or `ACTION_GET_CONTENT`, whether or not you have temporary read permissions for that contact will vary by contact-picking app.
I have read that appliaction is granted required permissions when user selects contact by hand. However on some phones this does not work (HTC EVO 3D).
There is no requirement that all contact-picking apps grant you temporary read access to the contact. In fact, I am unclear if third-party contact managers would have the ability to grant you temporary read access to the contact.
Is there a workaround such is ability to ask for this permission at runtime ?
You cannot change your mix of candidate permissions at runtime.
Your choices are:
Always ask for `READ_CONTACTS` in the manifest. This ensures you can do what you want, at the cost of requesting another permission, one that prospective users might not like.
Handle the `SecurityException` and simply do without the data that you are trying to `query()`, if that data is not essential.
Write a separate app with the `READ_CONTACTS` permission that can serve as a "plugin" for your app, securely retrieving contact data on behalf of your main app. You can then route users who get the `SecurityException` to install your contacts plugin. This is tricky to write without introducing security flaws, so I would encourage you to use either of the other options.
Problem
I have a HTC ONE M7 (GPE 4.2.2) and HTC EVO 3D (4.0.3) HTC Sense 3.6 HTC ONE does not need: ``` <uses-permission android:name="android.permission.READ_CONTACTS" /> ``` on HTC EVO 3D however, following code throws an exception: ``` public static String getPhoneNumberFromIntent(Context context, Intent data) throws SecurityException { String contactNumber = null; final Uri contactUri = data.getData(); if (contactUri != null) { Cursor c = null; try { // Read contact number from contacts provider String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER}; c = context.getContentResolver().query(contactUri, projection, null, null, null); if (c != null && c.moveToFirst()) { int maxNumberLength = context.getResources().getInteger(R.integer.max_phone_number_cze); contactNumber = cutOnlyLastPhoneNumberDigits(c.getString(0), maxNumberLength); } } finally { if (c != null) { c.close(); } } } return contactNumber; } ``` ``` java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.HtcContactsProvider2 uri content://com.android.contacts/data/2158 from pid=14938, uid=10125 requires android.permission.READ_CONTACTS ``` I have read that appliaction is granted required permissions when user selects contact by hand. However on some phones this does not work (HTC EVO 3D). Why is this happending? Is there a workaround such is ability to ask for this permission at runtime ?
