android.permission.READ_PHONE_STATE权限出现SecurityException异常

發送簡訊使用android.permission.READ_PHONE_STATE权限出现SecurityException异常

READ_PHONE_STATE的权限问题，尽管在manifest中添加了该权限，仍然会报权限不足

READ_PHONE_STATE这个权限在Android6.0（Api 23）及以上的版本，不仅需要在manifest中添加权限，还需要在运行时请求权限。

动态请求权限：

int permissionCheck = ContextCompat.checkSelfPermission(this,Manifest.permission.READ_PHONE_STATE);

if (permissionCheck != PackageManager.PERMISSION_GRANTED) {

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

    }
//----------------------------------------------------------------------------------

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_READ_PHONE_STATE:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                //TODO
            }
            break;
        default:
            break;
    }
}
