android - How to know if user has disabled Picture in Picture feature permission?

Question

and here is another example:

from the screenshot above we see user is able to disable picture in picture mode. you can find it in the "special app access" screen on the emulator api 27 . How can i detect if user has disabled this feature ?

i tried checking the following but it does not work:

packageManager.hasSystemFeature(PackageManager.FEATURE_PICTURE_IN_PICTURE)

compiler states that AppOpsManager cannot be found. any ideas ?

Answer 1

就像 AlexTa 说的。但我想实际编写代码以节省一些时间：

private fun hasPermission(): Boolean {
    val appOps = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager
    } else {
        return false
    }
    return appOps.checkOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, android.os.Process.myUid(), packageName) == AppOpsManager.MODE_ALLOWED
}

Answer 2

试试看AppOpsManager.checkOp (String op, int uid, String packageName)，OPSTR_PICTURE_IN_PICTURE操作在op哪里。如果支持画中画操作，该方法应返回MODE_ALLOWED常量。

我可能会迟到，但这是答案

private fun hasPermission(): Boolean {
    val appOps = getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager?
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            appOps?.unsafeCheckOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, android.os.Process.myUid(), packageName) == AppOpsManager.MODE_ALLOWED
        } else {
            appOps?.checkOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, android.os.Process.myUid(), packageName) == AppOpsManager.MODE_ALLOWED
        }
    } else {
        false
    }
}
