Android API级别23中的Settings.System API行为 [英] Settings.System API behaviour in Android API level 23

问题描述

在我的使用targetSdkVersion为23的应用程序中，同时使用API​​ Settings.System.putString().

In my application with targetSdkVersion as 23, while using the API Settings.System.putString().

引发以下错误并导致应用崩溃
"AndroidRuntime:java.lang.IllegalArgumentException:您不能将设置保留在安全设置中."

Following error is being thrown and app crashes
"AndroidRuntime: java.lang.IllegalArgumentException: You cannot keep your settings in the secure settings."

在
尝试解决方案后 无法获得WRITE_SETTINGS权限
并授予该应用在ACTION_MANAGE_WRITE_SETTINGS打开的屏幕中的写入权限.该应用程序仍然收到错误您无法将设置保留在安全设置中".

After trying solution at
Can't get WRITE_SETTINGS permission
and granting the app write permission in screen opened by ACTION_MANAGE_WRITE_SETTINGS. The app still gets the error "You cannot keep your settings in the secure settings".

现在是否仅对OEM开发的应用程序请求WRITE_SETTINGS权限? 有解决方案吗?

Is requesting the WRITE_SETTINGS permission now only for apps developed by OEMs ? Is there a solution possible ?

共享示例代码，已在具有M OS的Nexus 5设备上进行了测试.

    android:minSdkVersion="17"  
    android:targetSdkVersion="23"  
    uses-permission android:name="android.permission.WRITE_SETTINGS"

代码段:

protected void onResume() {
    super.onResume();
    boolean canDo =  Settings.System.canWrite(this);
    if (false == canDo)
    {
        Intent grantIntent = new   Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
        startActivity(grantIntent);
    }
    else
    {   
        Settings.System.putString(this.getContentResolver(),
            "test.hemant", "hemantval");
    }

推荐答案

您的代码在所有版本的Android上都将失败.如果它可以在Android 6.0之前运行，那么显然该错误已得到修复.

Your code should fail on all versions of Android. If it worked prior to Android 6.0, that was a bug that apparently just got fixed.

Settings.System用于平台定义的设置.您不能在其中放置任意设置，例如test.hemant.

Settings.System is for platform-defined settings. You cannot put arbitrary settings in there, such as test.hemant.
