android - 如何在 android 6.0 中赋予权限 com.sec.android.provider.badge.permission.READ 或 WRITE

Question

当通知来自服务器时，我正在尝试在应用程序图标上显示徽章。

我遇到了这个异常:

Caused by: java.lang.SecurityException: Permission Denial: opening provider com.sec.android.provider.badge.BadgeProvider from ProcessRecord{ab1124 10588:com.rehq.app/u0a175} (pid=10588, uid=10175) requires com.sec.android.provider.badge.permission.READ or com.sec.android.provider.badge.permission.WRITE

从 Android 6.0 开始，您需要在需要权限之前在运行时请求权限。

下面的示例是针对 WRITE 权限的(我猜你想在应用程序图标上添加一个徽章，通常你不需要 READ 权限 - 如果你需要它，你可以像写许可)

首先在 list 中添加您的权限:

<uses-permission android:name="com.sec.android.provider.badge.permission.WRITE"/>

然后你可以像这样在运行时检查它们是否被授予:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M 
            && ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_SETTINGS) != PackageManager.PERMISSION_GRANTED) {
        //permissions not granted -> request them
        requestPermissions(new String[] {Manifest.permission.WRITE_SETTINGS}, YOUR_REQUEST_CODE);
} else {
        //permissions are granted - do your stuff here :)
}

结果将在 onRequestPermissionResult 中可用:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    if (requestCode == YOUR_REQUEST_CODE) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_GRANTED) {
            //permissions granted -> do your stuff ;-)
        }
        //Permission not granted -> react to it!
        return;
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
