Android：使用 TYPE_APPLICATION_OVERLAY window 类型 2038 的权限被拒绝

Question

我试图创建一个高于其他应用程序的视图：

WindowManager.LayoutParams paramsDirectorView = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

我查看了其他回复，发现 "drawing over applications" 的以下内容：

清单中有 android.permission.SYSTEM_ALERT_WINDOW
我正在做 Settings.canDrawOverlays(this) 检查 返回 true.
我已经完成了这里的所有内容permission denied for window type

我仍然收到“-- window 类型 2038 的权限被拒绝”错误。到目前为止，我正在使用 TYPE_PHONE 并且它可以工作，但它已被弃用并说要使用 TYPE_APPLICATION_OVERLAY。有人可以跟进吗，因为 TYPE_PHONE 答案不是真正的解决方案，而是 Android O.

中弃用的 "patch work" 解决方案

我运行 Android 7.1.2

android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@1f47e89 -- permission denied for window type 2038 at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:3344) at android.app.ActivityThread.-wrap21(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1583) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6121) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:889) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:779) Caused by: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@1f47e89 -- permission denied for window type 2038 at android.view.ViewRootImpl.setView(ViewRootImpl.java:703) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:342) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:93) at HeadService.TwoViewManager.(TwoViewManager.java:99) at HeadService.UIHeadService.onStartCommand(UIHeadService.java:65) at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:3327) at android.app.ActivityThread.-wrap21(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1583) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6121) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:889) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:779)

Answer 1

尝试将 WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY 更改为 WindowManager.LayoutParams.TYPE_PHONE?

Answer 2

您是否通过调用以下意图请求运行时权限？

private void requestOverlayPermission() {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.M) {
        return;
    }

    Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
    myIntent.setData(Uri.parse("package:" + getPackageName()));
    startActivityForResult(myIntent, APP_PERMISSIONS);
}

然后在 onActivityResult() 中检查 Settings.canDrawOverlays(this) 是否为真，否则通过调用上述方法再次请求权限。

Answer 3

Source SYSTEM_ALERT_WINDOW 字符串 SYSTEM_ALERT_WINDOW 允许应用创建 windows 使用类型 TYPE_APPLICATION_OVERLAY，显示在所有其他应用之上。很少有应用程序应该使用此权限；这些 windows 用于与用户进行系统级交互。

注意：如果应用面向 API 级别 23 或更高级别，则应用用户必须通过权限管理屏幕明确向应用授予此权限。该应用通过发送带有操作 ACTION_MANAGE_OVERLAY_PERMISSION 的意图请求用户的批准。应用程序可以通过调用 Settings.canDrawOverlays().

来检查它是否有这个权限

我遇到了完全相同的问题。我想你应该区分目标（奥利奥之前和之后）

int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
     LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
        LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}

params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        LAYOUT_FLAG,
        WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

我在服务中遇到了完全相同的问题 class（在 Marshmallow 之前和之后）。

if (Build.VERSION.SDK_INT >= 23) {
    if (!Settings.canDrawOverlays(this)) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
          Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, 1234);
    }
} else {
    startService(new Intent(SplashActivity.this,                     
    CheckServicesForApps.class));
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1234) {
            startService(new Intent(SplashActivity.this, 
            CheckServicesForApps.class));

    }
}

public class CheckServicesForApps extends Service {
    private Context context = null;

    @Override
    public void onCreate() {
        super.onCreate();

        ImageView imageView = new ImageView(context);
        imageView.setVisibility(View.GONE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            try {
                windowManager = (WindowManager)getSystemService(WINDOW_SERVICE);

                //here is all the science of params
                final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                        WindowManager.LayoutParams.WRAP_CONTENT,

            params.gravity = Gravity.TOP | Gravity.CENTER;
            params.x = ((getApplicationContext().getResources().getDisplayMetrics().widthPixels) / 2);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
        layoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
    }else {
        layoutParams.type = WindowManager.LayoutParams.TYPE_PHONE;
