# android5 系统服务安装应用与设置HOME #

## 应用安装 ##

private void appInstall(String path) { 
      if(debug)Log.d(TAG,"appInstall file: " + path);
      PackageManager pm = getPackageManager();
          int installFlags = PackageManager.INSTALL_REPLACE_EXISTING | PackageManager.INSTALL_ALLOW_DOWNGRADE;
      File apkfile = new File(path);
      InstallObserver observer = new InstallObserver();
      pm.installPackage(Uri.fromFile(apkfile),observer,installFlags,null);
    }
    
    private class InstallObserver extends PackageInstallObserver { 
        @Override
        public void onPackageInstalled(String basePackageName, int returnCode, String msg, Bundle extras) { 
          String defHome = "com.android.launcher3";
          if (debug)Log.d(TAG, "InstallObserver onPackageInstalled basePackageName:" + basePackageName);
          checkHome(basePackageName);
        }
    }

appInstall函数入参为apk文件绝对路径例如/stoarge/sdcard1/home.apk

## 设置HOME并启动 ##

private void checkHome(String pakname) { 
      PackageManager mPm = getPackageManager();
          ArrayList<ResolveInfo> homeActivities = new ArrayList<ResolveInfo>();
          ComponentName currentDefaultHome  = mPm.getHomeActivities(homeActivities);
          if(debug)Log.d(TAG,"homeActivities.size(): " + homeActivities.size());
          if(homeActivities.size() > 1) { 
            ComponentName[] mHomeComponentSet = new ComponentName[homeActivities.size()];
            ComponentName homeactivityName = null;
          for (int i = 0; i < homeActivities.size(); i++) { 
              final ResolveInfo candidate = homeActivities.get(i);
              final ActivityInfo info = candidate.activityInfo;
              ComponentName activityName = new ComponentName(info.packageName, info.name);
              mHomeComponentSet[i] = activityName;
              if(pakname.equals(info.packageName))
                homeactivityName = activityName;
            }
            if(debug)Log.d(TAG,"homeactivityName: " + homeactivityName);
            if(homeactivityName != null) { 
            IntentFilter mHomeFilter = new IntentFilter(Intent.ACTION_MAIN);
          mHomeFilter = new IntentFilter(Intent.ACTION_MAIN);
          mHomeFilter.addCategory(Intent.CATEGORY_HOME);
          mHomeFilter.addCategory(Intent.CATEGORY_DEFAULT);
              mPm.replacePreferredActivity(mHomeFilter, IntentFilter.MATCH_CATEGORY_EMPTY,
                  mHomeComponentSet, homeactivityName);
          Intent myint = new Intent();
          PackageManager pm = getPackageManager();
          myint = pm.getLaunchIntentForPackage(pakname);
          myint.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          //myint.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
          startActivity(myint);
              }
          }
    }

checkHome入参为应用包名，获取到home应用列表后其中如果包含pakname就设置pakname为默认HOME  
并启动，设备重启就默认就会使用这个HOME  
需要包含的系统包名如下

import android.app.Service;
    import android.content.Intent;
    import android.os.IBinder;
    import android.util.Log;
    
    import java.io.File;
    import java.io.IOException;
    import android.net.Uri;
    import android.app.PackageInstallObserver;
    import android.os.Bundle;
    import android.os.UserHandle;
    import android.os.Handler;
    import android.content.pm.PackageManager;
    import android.content.pm.PackageManager.NameNotFoundException;
    import android.content.pm.PackageParser.PackageParserException;
    import android.content.pm.ApplicationInfo;
    import android.content.pm.PackageInfo;
    import android.content.pm.ResolveInfo;
    import java.util.ArrayList;
    import java.util.List;
    import android.content.IntentFilter;
    import android.content.ComponentName;
    import android.content.pm.ActivityInfo;
    import android.content.BroadcastReceiver;
    import android.content.Context;
