Packet安装，卸载广播与卸载检测操作代码

安装，卸载广播

• 类：PackageInstallReceiver

package com.biabia.club.testuninstalllistener.receiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.util.Log;

public class PackageInstallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //接收安装广播
        if (intent.getAction().equals(Intent.ACTION_PACKAGE_ADDED)) {
            String packageName = intent.getData().getSchemeSpecificPart();
        }
        //接收卸载广播
        if (intent.getAction().equals(Intent.ACTION_PACKAGE_REMOVED)) {
            String packageName = intent.getData().getSchemeSpecificPart();
            boolean isReplace = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
        }
        //接收升级更新广播
        if (intent.getAction().equals(Intent.ACTION_PACKAGE_REPLACED)) {
            String packageName = intent.getData().getSchemeSpecificPart();
        }
    }
    public void register(Context context) {
        context.registerReceiver(this, getIntentFilter());
    }

    public void unregister(Context context) {
        context.unregisterReceiver(this);
    }
    public IntentFilter getIntentFilter() {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
        intentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED);
        intentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED);
        intentFilter.addDataScheme("package");
        return intentFilter;
    }
}

• PackageUtils 中卸载与检测操作

public class PackageUtils {
    private static PackageUtils instance;

    public static PackageUtils getInstance(){
        if(instance==null){
            instance=new PackageUtils();
        }
        return instance;
    }
    /**
     * 卸载指定包名的应用
     * @param packageName
     */
    public boolean uninstall(String packageName, Context context) {
        Context appContext = context.getApplicationContext();
        boolean b = checkApp(packageName,context);
        if (b) {
            Uri packageURI = Uri.parse("package:".concat(packageName));
            Intent intent = new Intent(Intent.ACTION_DELETE);
            intent.setData(packageURI);
            appContext.startActivity(intent);
            return true;
        }
        return false;
    }

    /**
     * 判断该包名的应用是否安装
     * @param packageName
     * @return
     */
    private boolean checkApp(String packageName, Context context) {
        if (packageName == null || "".equals(packageName)) {
            return false;
        }
        try {
            context.getPackageManager()
                    .getApplicationInfo(packageName, PackageManager.MATCH_UNINSTALLED_PACKAGES);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
            Log.i(TAG, "Test:" + e.toString());
        }
        return false;
    }
}
