一.多个launcher 启动设置默认launcher的核心类
1.通过ResolverActivity.java设置为默认Launcher
2.通过ActivityManagerService.java设置为默认Launcher主要修改getHomeIntent()，将其替换成需要默认的Launcher即可。
在Android系统中，设置默认Launcher（启动器）是一个涉及系统权限和配置的过程。通常，这个过程不是通过简单地修改几个文件或设置就能完成的，因为它需要系统级别的权限。不过，我可以概述一下在Android源码级别如何设置或允许用户选择默认Launcher的大致步骤。
第一部分、android10之前
一.多个launcher 启动设置默认launcher的核心类
代码路径：frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
2.多个launcher 启动设置默认launcher的核心功能实现和分析
通过在系统中内置其他Launcher时，在系统进入启动Launcher的过程中，会在ResolverActivity.java中，首先查询系统中由几个Launcher,当有多个Launcher时，会让用户选择启动的Launcher,然后作为默认启动Launcher. 所以就来分析该怎么设置默认Launcher,而不用用户选择启动Launcher.
先来看下ResolverActivity.java的相关源码

在ResolverActivity.java中的onCreate中首先读取系统中的Home属性的Launcher列表，然后在
ResolveListAdapter中展示Launcher的列表，所以可以在这些直接设置默认的Launcher，然后finish掉这个页面，直接进入默认Launcher页面

}第二部分、android10之后
一、Launcher应用内置并设置为默认Launcher
主要利用ResolverActivity.java或ActivityManagerService.java来实现，接下来我将分别举例说明：
1.通过ResolverActivity.java设置为默认Launcher
主要是由addPreferredActivity设置默认Launcher实现。
改法一：
代码路径：frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
以下基于Android11代码：
protected void onCreate(Bundle savedInstanceState, Intent intent,
CharSequence title, int defaultTitleRes, Intent[] initialIntents,
List<ResolveInfo> rList, boolean supportsAlwaysUseOption) {
setTheme(appliedThemeResId());
super.onCreate(savedInstanceState);
//add
if(mResolvingHome){
setDefaultLauncher();
finish();
return;
}
//add
...
}
private void setDefaultLauncher() {
try {
final PackageManager pm = getPackageManager();
String defPackageName = "com.android.launcher3";//默认launcher包名
String defClassName = "com.android.searchlauncher.SearchLauncher";//默认launcher类名
IntentFilter filter = new IntentFilter();
filter.addAction("android.intent.action.MAIN");
filter.addCategory("android.intent.category.HOME");
filter.addCategory("android.intent.category.DEFAULT");
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
List<ResolveInfo> list = new ArrayList<ResolveInfo>();
list = pm.queryIntentActivities(intent, 0);
final int N = list.size();
ComponentName[] set = new ComponentName[N];
int bestMatch = 0;
for (int i = 0; i < N; i++) {
ResolveInfo r = list.get(i);
set[i] = new ComponentName(r.activityInfo.packageName,
r.activityInfo.name);
if (r.match > bestMatch) bestMatch = r.match;
}
ComponentName preActivity = new ComponentName(defPackageName, defClassName);
pm.addPreferredActivity(filter, bestMatch, set, preActivity);
} catch (Exception e) {
e.printStackTrace();
}
}改法二：
代码路径：frameworks/base/services/core/java/com/android/server/am/ActivityManagerService.java
boolean startHomeActivityLocked(int userId, String reason) {
setDefaultLauncher();//调用设置默认launcher方法
SystemProperties.set("persist.sys.boot.bootcomplete","1");
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;
}
...
...
}
private void setDefaultLauncher() {
boolean mFirstLaunch = true;
String packageName = "包名";//launcher包名
String className = "类名";
if ((packageName != null && packageName.trim().length() > 1) && (className != null && className.trim().length() > 0)) {
if(mFirstLaunch){
IPackageManager pm = ActivityThread.getPackageManager();
ArrayList<IntentFilter> intentList = new ArrayList<IntentFilter>();
ArrayList<ComponentName> cnList = new ArrayList<ComponentName>();
mContext.getPackageManager().getPreferredActivities(intentList, cnList, null);
IntentFilter dhIF;
for(int i = 0; i < cnList.size(); i++){
dhIF = intentList.get(i);
if(dhIF.hasAction(Intent.ACTION_MAIN) &&
dhIF.hasCategory(Intent.CATEGORY_HOME)) {
mContext.getPackageManager().clearPackagePreferredActivities(cnList.get(i).getPackageName());
}
}
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
List<ResolveInfo> list = new ArrayList<ResolveInfo>();
try {
list = pm.queryIntentActivities(intent,
intent.resolveTypeIfNeeded(mContext.getContentResolver()),
PackageManager.MATCH_DEFAULT_ONLY,UserHandle.getCallingUserId()).getList(); //add .getList()
}catch (RemoteException e) {
throw new RuntimeException("Package manager has died", e);
}
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_MAIN);
filter.addCategory(Intent.CATEGORY_HOME);
filter.addCategory(Intent.CATEGORY_DEFAULT);
final int N = list.size();
ComponentName[] set = new ComponentName[N];
int bestMatch = 0;
for (int i = 0; i < N; i++)
{
ResolveInfo r = list.get(i);
set[i] = new ComponentName(r.activityInfo.packageName,
r.activityInfo.name);
if (r.match > bestMatch) bestMatch = r.match;
}
ComponentName launcher = new ComponentName(packageName, className);
try{
pm.addPreferredActivity(filter, bestMatch, set, launcher,UserHandle.getCallingUserId());
} catch (RemoteException e) {
throw new RuntimeException("Package manager has died", e);
}
}
}
}2.通过ActivityManagerService.java设置为默认Launcher
主要修改getHomeIntent()，将其替换成需要默认的Launcher即可。
代码路径：frameworks\base\services\core\java\com\android\server\am\ActivityManagerService.java
改法一(常规)：
Intent getHomeIntent() {
//add
Settings.Global.putInt(mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);
Settings.Secure.putInt(mContext.getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);
String defStartPkg = "你的包名";
Intent queryIntent = new Intent();
final PackageManager mPm = mContext.getPackageManager();
queryIntent.addCategory(Intent.CATEGORY_HOME);///没有home可去掉
queryIntent.addCategory(Intent.CATEGORY_LAUNCHER);
queryIntent.setAction(Intent.ACTION_MAIN);
List<ResolveInfo> homeActivities = mPm.queryIntentActivities(queryIntent, 0);
if(homeActivities != null) {
int activityNum = homeActivities.size();
ComponentName[] set = new ComponentName[activityNum];
for(int i = 0; i < activityNum; i++){
ResolveInfo info = homeActivities.get(i);
set[i] = new ComponentName(info.activityInfo.packageName, info.activityInfo.name);
if(defStartPkg.equals(info.activityInfo.packageName)){
Intent intentaa = new Intent(mTopAction, mTopData != null ? Uri.parse(mTopData) : null);
intentaa.setComponent(set[i]);
intentaa.addCategory(Intent.CATEGORY_HOME);
return intentaa;
}
}
}
//add
Intent intent = new Intent(mTopAction, mTopData != null ? Uri.parse(mTopData) : null);
intent.setComponent(mTopComponent);
if (mFactoryTest != FactoryTest.FACTORY_TEST_LOW_LEVEL) {
intent.addCategory(Intent.CATEGORY_HOME);
}
return intent;
}改法二(简化）：
Intent getHomeIntent() {
Intent intent = new Intent(mTopAction, mTopData != null ? Uri.parse(mTopData) : null);
//add
//intent.setComponent(mTopComponent);
intent.setComponent(new ComponentName("包名", "类名"));
//add
intent.addFlags(Intent.FLAG_DEBUG_TRIAGED_MISSING);
if (mFactoryTest != FactoryTest.FACTORY_TEST_LOW_LEVEL) {
intent.addCategory(Intent.CATEGORY_HOME);
}
return intent;
}二、普通应用内置并设置为默认Launcher
因为这类应用通常没有android.intent.category.HOME这个Category，故无法使用上述常规方式来设置为默认应用，使用需要我们另辟蹊径，这边也是为各位提供两种方法。
1.强制替换
首先将应用设置为默认开机启动，但因为没有android.intent.category.HOME这个Category所以提供通过ResolverActivity.java设置是不行的，需要通过修改ActivityManagerService.java来实现，只要把改法一中的queryIntent.addCategory(Intent.CATEGORY_HOME);注释掉即可：
Intent getHomeIntent() {
//add
Settings.Global.putInt(mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);
Settings.Secure.putInt(mContext.getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);
String defStartPkg = "你的包名";
Intent queryIntent = new Intent();
final PackageManager mPm = mContext.getPackageManager();
//queryIntent.addCategory(Intent.CATEGORY_HOME);///没有home可去掉
queryIntent.addCategory(Intent.CATEGORY_LAUNCHER);
queryIntent.setAction(Intent.ACTION_MAIN);
List<ResolveInfo> homeActivities = mPm.queryIntentActivities(queryIntent, 0);
if(homeActivities != null) {
int activityNum = homeActivities.size();
ComponentName[] set = new ComponentName[activityNum];
for(int i = 0; i < activityNum; i++){
ResolveInfo info = homeActivities.get(i);
set[i] = new ComponentName(info.activityInfo.packageName, info.activityInfo.name);
if(defStartPkg.equals(info.activityInfo.packageName)){
Intent intentaa = new Intent(mTopAction, mTopData != null ? Uri.parse(mTopData) : null);
intentaa.setComponent(set[i]);
intentaa.addCategory(Intent.CATEGORY_HOME);
return intentaa;
}
}
}
//add
Intent intent = new Intent(mTopAction, mTopData != null ? Uri.parse(mTopData) : null);
intent.setComponent(mTopComponent);
if (mFactoryTest != FactoryTest.FACTORY_TEST_LOW_LEVEL) {
intent.addCategory(Intent.CATEGORY_HOME);
}
return intent;
}通过上面的修改就可以开机默认启动了，但是会出现按home、recent、back键会退出应用从而进入原生Launcher的情况，所以我们需要对这些按键进行拦截定制：
代码路径：frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java
mHomeIntent = new Intent(Intent.ACTION_MAIN, null);
mHomeIntent.addCategory(Intent.CATEGORY_HOME);
//add
ComponentName mHomecom = new ComponentName("包名", "类名");
mHomeIntent.setComponent(mHomecom);
//add
mHomeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
@Override
public long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {
....
....
//add
if(keyCode == KeyEvent.KEYCODE_BACK){ if(getClsName(mContext).equals("com.ryanheise.audioservice.AudioServiceFragmentActivity")
&&(getInputMethodWindowVisibleHeightLw()==0)){
return -1;
}
}
//add
....
....
}
private String getClsName(Context context) {
try {
ActivityManager am = context.getSystemService(ActivityManager.class);
List<ActivityManager.RunningTaskInfo> tasks = am.getRunningTasks(1);
return tasks.get(0).topActivity.getClassName();
} catch (Exception e) {
//ignore
}
return "";
}代码路径：SystemUI\src\com\android\systemui\recents\RecentsActivity.java
import android.content.ComponentName;
Intent homeIntent = new Intent(Intent.ACTION_MAIN, null);
homeIntent.addCategory(Intent.CATEGORY_HOME);
ComponentName mHomecom = new ComponentName("包名", "类名");
homeIntent.setComponent(mHomecom);
homeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);2.添加属性
