修改app的默认设置（包括修改默认launcher）

1、改为自己的launcher

ComponentName component = new ComponentName(

context.getPackageName(),
MainActivity.class.getName());//红色为自己的launcher入口

ComponentName[] components = new ComponentName[] {

new ComponentName("com.android.launcher",

"com.android.launcher2.Launcher"), component };

pm.clearPackagePreferredActivities("com.android.launcher");//清除默认launcher

pm.addPreferredActivity(filter, IntentFilter.MATCH_CATEGORY_EMPTY,

components, component);

2、改为系统的launcher

ComponentName component = new ComponentName("com.android.launcher",

"com.android.launcher2.Launcher");

ComponentName[] components = new ComponentName[] {

new ComponentName(context.getPackageName(), MainActivity.class.getName()), component };

pm.clearPackagePreferredActivities("com.android.launcher");

pm.addPreferredActivity(filter, IntentFilter.MATCH_CATEGORY_EMPTY,

components, component);
