Android(安卓)监控程序安装和删除的实现

本文主要讨论如何监控 Android 程序包的安装和删除

Android系统的安装方式我在《Android 应用程序安装方式的详细调研》一文中已经做了详细的阐述，链接如下

基于这些安装方式，我们如何对系统进行的安装进行监控呢？

通过阅读Android SDK里关于intent.action这部分里面的描述，我们可以找到一些与package相关的系统广播
[c-sharp] android.intent.action.PACKAGE_ADDED
android.intent.action.PACKAGE_CHANGED
android.intent.action.PACKAGE_DATA_CLEARED
android.intent.action.PACKAGE_INSTALL
android.intent.action.PACKAGE_REMOVED
android.intent.action.PACKAGE_REPLACED
android.intent.action.PACKAGE_RESTARTED
android.intent.action.PACKAGE_ADDED
android.intent.action.PACKAGE_CHANGED
android.intent.action.PACKAGE_DATA_CLEARED
android.intent.action.PACKAGE_INSTALL
android.intent.action.PACKAGE_REMOVED
android.intent.action.PACKAGE_REPLACED
android.intent.action.PACKAGE_RESTARTED
其中
ACTION_PACKAGE_ADDED
在SDK里的描述是
Broadcast Action: A new application package has been installed on the device.
ACTION_PACKAGE_REMOVED
在SDK里的描述是
Broadcast Action: An existing application package has been removed from the device.
ACTION_PACKAGE_REPLACED
在SDK里的描述是
Broadcast Action: A new version of an application package has been installed, replacing an existing version that was previously installed.

通过这三个广播消息我们已经可以监控到Android 应用程序的安装和删除

详细的实现代码如下

getBroadcast.java[c-sharp] package zy.Broadcast; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.widget.Toast; public class getBroadcast extends BroadcastReceiver {         @Override         public void onReceive(Context context, Intent intent) {                                   if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){                     Toast.makeText(context, "有应用被添加", Toast.LENGTH_LONG).show();             }                 else  if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){                     Toast.makeText(context, "有应用被删除", Toast.LENGTH_LONG).show();             }              /*   else  if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被改变", Toast.LENGTH_LONG).show();            }*/                 else  if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){                     Toast.makeText(context, "有应用被替换", Toast.LENGTH_LONG).show();             }                /* else  if(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被重启", Toast.LENGTH_LONG).show();            }*/               /*  else  if(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){                    Toast.makeText(context, "有应用被安装", Toast.LENGTH_LONG).show();            }*/                      }         }

package zy.Broadcast;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class getBroadcast extends BroadcastReceiver {        @Override        public void onReceive(Context context, Intent intent) {                                if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被添加", Toast.LENGTH_LONG).show();            }                else  if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被删除", Toast.LENGTH_LONG).show();            }             /*   else  if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被改变", Toast.LENGTH_LONG).show();            }*/                else  if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被替换", Toast.LENGTH_LONG).show();            }               /* else  if(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){                    Toast.makeText(context, "有应用被重启", Toast.LENGTH_LONG).show();            }*/              /*  else  if(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){                    Toast.makeText(context, "有应用被安装", Toast.LENGTH_LONG).show();            }*/                   }      }

然后在AndroidManifest.xml中声明这几个Action的<intent-filter>即可在系统里捕获这些广播消息
具体的源代码如下

     </manifest>  <?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="zy.Broadcast"      android:versionCode="1"      android:versionName="1.0">    <application android:icon="@drawable/icon" android:label="@string/app_name">        <activity android:name=".Broadcast"                  android:label="@string/app_name">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>      <receiver android:name="getBroadcast" android:enabled="true" >         <intent-filter>          <action android:name="android.intent.action.PACKAGE_ADDED"></action>          <!-- <action android:name="android.intent.action.PACKAGE_CHANGED"></action>-->          <action android:name="android.intent.action.PACKAGE_REMOVED"></action>          <action android:name="android.intent.action.PACKAGE_REPLACED"></action>          <!-- <action android:name="android.intent.action.PACKAGE_RESTARTED"></action>-->        <!--    <action android:name="android.intent.action.PACKAGE_INSTALL"></action>-->            <data android:scheme="package"></data>              </intent-filter></receiver>    </application>    <uses-sdk android:minSdkVersion="7" />   </manifest>

把程序安装之后，系统就会注册这个BroadcastReceiver
然后有应用安装删除替换操作时时，就会弹出Toast提示
以上这样，我们就可以实现监控Android 应用程序的安装过程

至于拦截安装过程，我也正在研究中，大家有好的idea可以与我分享，谢谢
