java.lang.SecurityException: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord

先在AndroidMainfest.xml中添加权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>

然后在需要申请权限的地方添加以下代码

if(ContextCompat.checkSelfPermission(this,Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED){requestPermissions(new String[]{Manifest.permission.READ_CONTACTS},1);}
