Android7.0 MTK设置默认桌面
本文实例为大家分享了Android7.0MTK设置默认桌面的具体代码，供大家参考，具体内容如下
项目需求:客户安装自己公司的桌面apk，安装完成后自动设置为默认桌面且不弹出始终和仅一次的弹框
1.找到安装应用的文件
frameworks\base\services\core\java\com\android\server\pm\PackageManagerService.java
try{
PackageParser.PackagenewPackage=scanPackageTracedLI(pkg,policyFlags,scanFlags,
System.currentTimeMillis(),user);
updateSettingsLI(newPackage,installerPackageName,null,res,user);
if(res.returnCode==PackageManager.INSTALL_SUCCEEDED){
prepareAppDataAfterInstallLIF(newPackage);
Log.d("yh","pkgName"+pkgName);
//由于客户的应用保密这里使用点心桌面的包名---com.dianxinos.dxhome
if(pkgName.equals("com.dianxinos.dxhome")){
//发送广播
Intentintent=newIntent("android.intent.action.UPDATE_LANUCHER_APPS");
mContext.sendBroadcast(intent);
}
//------------------------
}else{
//Removepackagefrominternalstructures,butkeeparoundany
//datathatmighthavealreadyexisted
deletePackageLIF(pkgName,UserHandle.ALL,false,null,
PackageManager.DELETE_KEEP_DATA,res.removedInfo,true,null);
}
}catch(PackageManagerExceptione){
res.setError("Packagecouldn'tbeinstalledin"+pkg.codePath,e);
}
Trace.traceEnd(TRACE_TAG_PACKAGE_MANAGER);
}
2.由于设置默认桌面时，是在Settings中设置的所以广播接收者在settings中添加并设置默认桌面（添加文件–packages\apps\Settings\src\com\android\settings下—UpdateLanucherReceiver.java）
packagecom.android.settings;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.ComponentName;
importandroid.content.IntentFilter;
importandroid.content.pm.PackageManager;
importandroid.content.pm.ResolveInfo;
importjava.util.ArrayList;
importandroid.util.Log;
importandroid.content.pm.ActivityInfo;
importjava.util.List;
publicclassUpdateLanucherReceiverextendsBroadcastReceiver{
publicUpdateLanucherReceiver(){
}
@Override
publicvoidonReceive(Contextcontext,Intentintent){
if(intent.getAction().equals("android.intent.action.UPDATE_LANUCHER_APPS")){
Log.e("yhyh","onReceive");
finalPackageManagermPm=context.getPackageManager();
//点心桌面的包名类名com.dianxinos.dxhome/com.nd.hilauncherdev.launcher.Launcher设置默认桌面
ComponentNameDefaultLauncher=newComponentName("com.dianxinos.dxhome",
"com.nd.hilauncherdev.launcher.Launcher");
ArrayListhomeActivities=newArrayList();
ComponentNamecurrentDefaultHome=mPm.getHomeActivities(homeActivities);
ComponentName[]mHomeComponentSet=newComponentName[homeActivities.size()];
for(inti=0;i
