Answer 1

您必须自己申请许可。 如此guide

中所述

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.SEND_SMS)
    != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
        Manifest.permission.SEND_SMS)) {

        // 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.SEND_SMS},
            MY_PERMISSIONS_REQUEST_SEND_SMS);

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

如果您不想使用运行时权限，请在Gradle中将目标SDK版本设置为21.

在 Gradle 中添加目标SDK ，如下所示：

android {
    defaultConfig {
        .....
        .....
        targetSdkVersion 21
    }
}
