接收的意图和QUOT; android.settings.APPLICATION_DETAILS_SETTINGS＆QUOT;我的应用程序 [英] Receive intent "android.settings.APPLICATION_DETAILS_SETTINGS" for my app

问题描述

我想获得的包名和类名接收意图，但我不能够得到它。
我要让我的应用程序的安全，因此正在卸载之前询问密码。只有谁安装的应用程序，用户知道密码，所以只有他/她可以卸载该应用。

I want to get the package name and class name of the received intent, But am not able to get it. I want to make my app secure so it asks for password before being uninstalled. Only the user who Installed the app knows the password, so only he/she can uninstall the app.

我的code为接收器：

public class PackageReceiver extends BroadcastReceiver { 
@ Override 
public void onReceive (Context context, Intent intent) { 
if (intent.getAction().equals("android.settings.APPLICATION_DETAILS_SETTINGS")) { 
/ / TODO: 
//I want here to get this getAction working and then I want to fetch package and class of the intent
} 

} 
} 

清单：

<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.RESTART_PACKAGES"/> 
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> 

<Application 
android: icon = "@ drawable / ic_launcher" 
android: label = "Test"> 

<Receiver android: name = ". PackageReceiver" 
android: label = "@ string / app_name"> 
<intent-filter> 
<action android:name="android.settings.APPLICATION_DETAILS_SETTINGS" /> 
<data android:scheme="package" /> 
</ Intent-filter> 
</ Receiver> 
</ Application> 

请让我知道如果我错过任何权限，因为我不能得到这个工作。

Please let me know if I am missing any permission because I can not get this working.

推荐答案

当我们选择设置屏幕内特定的应用程序，该类型的广播：android.intent.action.QUERY_PACKAGE_RESTART与应用程序的包名解雇一个额外的。我想，你可以用它来火密码对话框。

When we select a particular app inside the settings screen, a broadcast of the type : android.intent.action.QUERY_PACKAGE_RESTART is fired with package name of the application as an extra. I think you could use that to fire the password dialog.

接收器code将是这样的：

The receiver code will be something like this :

public void onReceive(Context context, Intent intent) {
    String[] packageNames = intent.getStringArrayExtra("android.intent.extra.PACKAGES"); 

    if(packageNames!=null){
        for(String packageName: packageNames){
            if(packageName!=null && packageName.equals("our_app_package_name")){
                //Our app was selected inside settings. Fire Password Dialog. 
            }
        }
    }
}
