Android 11--设置第三方Launcher并默认 与 如何预置apk
1.0Ver
/frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
+ private void setDefaultLauncher() {
+ try {
+ final PackageManager pm = getPackageManager();
+
+ //String defPackageName = "com.android.launcher3";
+ String defPackageName = "com.demo.launcher3";
+ String defClassName;
+
+ //defClassName = "com.android.searchlauncher.SearchLauncher";
+ defClassName = "com.demo.launcher.MainActivity";
+
+ Log.i("deflauncher", "deflauncher : PackageName = " +
+ defPackageName + " ClassName = " + defClassName);
+
+ 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();
+ }
+ }
+
protected void onCreate(Bundle savedInstanceState, Intent intent,
CharSequence title, int defaultTitleRes, Intent[] initialIntents,
List<ResolveInfo> rList, boolean supportsAlwaysUseOption) {
setTheme(appliedThemeResId());
super.onCreate(savedInstanceState);
+ if(mResolvingHome){
+ setDefaultLauncher();
+ finish();
+ return;
+ }
+
...
2.0Ver
/frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
public final void onPostListReady(ResolverListAdapter listAdapter, boolean doPostProcessing,
boolean rebuildCompleted) {
...
if (isAutolaunching()) {
return;
}
+ //add start
+ if(setCustomerDefLauncher()){
+ return;
+ }
+ //add end
...
}
final boolean postRebuildListInternal(boolean rebuildCompleted) {
//...
//add start
if (rebuildCompleted && (setCustomerDefLauncher() || maybeAutolaunchActivity())) {
return true;
}
//add end
}
//add start
+ private boolean setCustomerDefLauncher(){
+ String defLauncher = "com.demo.launcher3";
+ int size = mMultiProfilePagerAdapter.getActiveListAdapter().getDisplayResolveInfoCount();
+ android.util.Log.d("TAG","setCustomerDefLauncher:"+size);
+ for (int i = 0; i<size; i++){
+ DisplayResolveInfo dInfo = mMultiProfilePagerAdapter.getActiveListAdapter().getDisplayResolveInfo(i);
+ if (null != dInfo && defLauncher.equals(dInfo.getResolveInfo().activityInfo.packageName)) {
+ Log.d("TAG", "find need set default launcher, set default launcher--->" + dInfo.getResolveInfo().activityInfo. packageName);
+ startSelected(i, true, false);
+ return true;
+ }
+ }
+ return false;
+ }
//add end
多个launcher时，防止闪屏
/frameworks/base/core/java/com/android/internal/app/ResolverListAdapter.java；
protected boolean rebuildList(boolean doPostProcessing) {
...
//add start
+ String defLauncher = "com.demo.launcher3;
+ for (ResolvedComponentInfo info : currentResolveList) {
+ ResolveInfo resolveInfo = info.getResolveInfoAt(0);
+ if (defLauncher.equals(resolveInfo.activityInfo.packageName)) {
+ currentResolveList = new ArrayList<>();
+ currentResolveList.add(info);
+ Log.d("tww", "find set default launcher--->" + resolveInfo.activityInfo.packageName);
+ break;
+ }
+ }
+ //add end
+
...
}
如果当前为Launcher3显示，然后从设置里面切换默认为第三方Launcher应用，在第三方应用中，点击导航栏返回按键时，会返回到Launcher3，是因为切换设置默认launcher后，前一个的任务栈还存在，需要删除
+import android.app.ActivityManager;
+import android.app.ActivityTaskManager;
+import android.os.RemoteException;
+ private void clearOldLauncherTask() {
+ ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
+ List<ActivityManager.RunningTaskInfo> list = activityManager.getRunningTasks(Integer.MAX_VALUE);
+ if (list != null) {
+ for (ActivityManager.RunningTaskInfo item : list) {
+ Log.d("tag", "--->" + item.configuration.windowConfiguration.getActivityType());
+ Log.d("tag", "--->" + item.realActivity.getPackageName());
+ //if(item.configuration.windowConfiguration.getActivityType() == WindowConfiguration.ACTIVITY_TYPE_HOME){}
+ if (item.realActivity.getPackageName().equals("com.android.launcher3")) {
+ final int tId = item.taskId;
+ try {
+ Log.d("tag", "tId--->" + tId);
+ ActivityTaskManager.getService().removeTask(tId);
+ } catch (RemoteException e) {
+ Log.d("tag", "--->RemoteException");
+ }
+ }
+ }
+ }
+ }
+
知道了怎么删除旧的Launcher 任务栈，还需要知道删除旧的Launcher任务栈Timing，
第一个Timing点，可以发送广播通知删除旧的
/packages/apps/PermissionController/src/com/android/permissioncontroller/role/model/HomeRoleBehavior.java
@Override
public void onHolderSelectedAsUser(@NonNull Role role, @NonNull String packageName,
@NonNull UserHandle user, @NonNull Context context) {
// Launch the new home app so the change is immediately visible even if the home button is
// not pressed.
Intent intent = new Intent(Intent.ACTION_MAIN)
.addCategory(Intent.CATEGORY_HOME)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
//add start
Intent launcherIntent = new Intent("xxxx.x.x.x.action");
launcherIntent.putExtra("launcher_package_name", packageName);
context.sendBroadcast(launcherIntent);
//add end
}
第二个Timing点
frameworks/base/services/core/java/com/android/server/role/RoleManagerService.java
@Override
public void addRoleHolderAsUser(@NonNull String roleName, @NonNull String packageName,
@RoleManager.ManageHoldersFlags int flags, @UserIdInt int userId,
@NonNull RemoteCallback callback) {
if (!mUserManagerInternal.exists(userId)) {
Slog.e(LOG_TAG, "user " + userId + " does not exist");
return;
}
userId = handleIncomingUser(userId, false, "addRoleHolderAsUser");
getContext().enforceCallingOrSelfPermission(Manifest.permission.MANAGE_ROLE_HOLDERS,
"addRoleHolderAsUser");
Preconditions.checkStringNotEmpty(roleName, "roleName cannot be null or empty");
Preconditions.checkStringNotEmpty(packageName, "packageName cannot be null or empty");
Objects.requireNonNull(callback, "callback cannot be null");
getOrCreateController(userId).onAddRoleHolder(roleName, packageName, flags,
callback);
//add start
if (roleName.equals("android.app.role.HOME")) {
Log.i("tag", "change value->packageName:" + packageName);
if (packageName.equals("com.android.launcher3")) {
SystemProperties.set("persist.sys.xxx", null);
} else {
SystemProperties.set("persist.sys.xxx", packageName);
}
//发送广播
}
//add end
}
第二个timing 早于第一个

Android预置Apk，Android.mk/Android.bp
预置apk，整个东西其实非常简单，因为系统本身它自己也内置不少apk,找到对应目录，查看它怎么写，.mk或.bp文件，依葫芦画瓢就行了！！！
系统应用：Browser2，Calendar等，一般都在packages目录下
build/make/target/product/handheld_product.mk
# /product packages
PRODUCT_PACKAGES += \
+ demo \
Browser2 \
Calendar \
Camera2 \
...
Android.bp

// this needs to be a privileged application
privileged: true, //当一个模块被标识为 privileged: true 时，它将被视为具有特权权限，
//可以访问系统级别的资源或执行特权操作。
// Make sure the build system doesn't try to resign the APK
