您已在运行时请求权限：

if (ContextCompat.checkSelfPermission(thisActivity,Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {


if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
        Manifest.permission.READ_EXTERNAL_STORAGE)) {

    // Show an explanation to the user *asynchronously* -- don't block
    // this thread waiting for the user's response! After the user
    // sees the explanation, try again to request the permission.

} else {

    // No explanation needed, we can request the permission.

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

    // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
    // app-defined int constant. The callback method gets the
    // result of the request.
}
}

然后再做您想做的事情（如果用户授予权限）：

这可能会有所帮助。我还注意到，您尚未在manifest.xxml文件中为reciver标记添加任何优先级。尝试添加它。现在我添加了我添加了优先级现在它工作正常'
