本文介绍了如何在Android 6.0中设置默认启动器，包括两种方法：1) 添加代码到ActivityManagerService.java，使得系统启动时默认使用指定的启动器应用；2) 修改PackageManagerService.java，通过系统属性判断并设置默认启动器。

1.设置默认Launcher，但不是唯一的，可以在设置里面去切换的方法。

frameworks\base\services\core\java\com\android\server\am\ActivityManagerService.java中的startHomeActivityLocked方法里面添加如下代码。

boolean startHomeActivityLocked(int userId, String reason) {
if (mFactoryTest == FactoryTest.FACTORY_TEST_LOW_LEVEL
&& mTopAction == null) {
// We are running in factory test mode, but unable to find
// the factory test app, so just sit around displaying the
// error message and don't try to start anything.
return false;
}

/**
* yf add
* set default launcher
*/
ComponentName DefaultLauncher=new
ComponentName("com.yougfeel.mywy","com.yougfeel.mywy.MainActivity"); //此处设置默认Launcher的包类名
//Slog.d(TAG,"set default launcher");

final PackageManager mPm = mContext.getPackageManager();
ArrayList<ResolveInfo> homeActivities = new ArrayList<ResolveInfo>();
ComponentName currentDefaultHome = mPm.getHomeActivities(homeActivities);
ComponentName[]mHomeComponentSet = new ComponentName[homeActivities.size()];

for (int i = 0; i < homeActivities.size(); i++) {
final ResolveInfo candidate = homeActivities.get(i);
//Slog.d(TAG,"homeActivities"+candidate);
final ActivityInfo info = candidate.activityInfo;
ComponentName activityName = new ComponentName(info.packageName, info.name);
mHomeComponentSet[i] = activityName;
}
IntentFilter mHomeFilter = new IntentFilter(Intent.ACTION_MAIN);
mHomeFilter.addCategory(Intent.CATEGORY_HOME);
mHomeFilter.addCategory(Intent.CATEGORY_DEFAULT);
List<ComponentName>Activities=new ArrayList();
mPm.replacePreferredActivity(mHomeFilter, IntentFilter.MATCH_CATEGORY_EMPTY,mHomeComponentSet, DefaultLauncher);
/**
* set default launcher end
*/

2.设置默认唯一的Launcher，在不去掉其他Launcher的情况下。
