修改app的默认设置（包括修改默认launcher）

标签：

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);
