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

[c-sharp] <?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_REMOVED"></action>
             <action android:name="android.intent.action.PACKAGE_REPLACED"></action>
             
           
               <data android:scheme="package"></data>
              </intent-filter>
</receiver>
    </application>
    <uses-sdk android:minSdkVersion="7" />

</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_REMOVED"></action>
          <action android:name="android.intent.action.PACKAGE_REPLACED"></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

删除应用

添加应用

有应用被替换

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
