Question

我正试图在通知来自服务器时在应用图标上显示徽章。

我得到了这个例外：

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

Answer 1

从Android 6.0开始，您需要在运行时请求权限。

以下示例适用于WRITE权限（我猜你想在应用图标上添加徽章，通常你不需要READ权限 - 如果你需要它，你可以申请它就像WRITE权限一样）

首先在Manifest中添加权限：

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

然后你可以检查它们是否在运行时被授予如下：

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中提供：

@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);
}
