ackageName,
resolveInfo.activityInfo.name);
if (defaultLauncher.getClassName().equals(
resolveInfo.activityInfo.name)) {
defaultMatch = resolveInfo.match;
}
}
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_MAIN);
filter.addCategory(Intent.CATEGORY_HOME);
filter.addCategory(Intent.CATEGORY_DEFAULT);
addPreferredActivity2(filter, defaultMatch, set,
defaultLauncher);
}
}
// TChip ZJ Add Above for Default Launcher
2.添加以下函数：
/**
- TChip ZJ Add for Default Launcher
*/
public void addPreferredActivity2(IntentFilter filter, int match,
ComponentName[] set, ComponentName activity) {
Log.d(“debug_default”, “addPreferredActivity2 is called.”);
// writer
synchronized (mPackages) {
Slog.i(TAG, "Adding preferred activity " + activity + “:”);
filter.dump(new LogPrinter(Log.INFO, TAG), " ");
mSettings.editPreferredActivitiesLPw(0).addFilter(
new PreferredActivity(filter, match, set, activity, true));
scheduleWriteSettingsLocked();
}
}
3.修改PackageManagerService.java的函数findPreferredActivity：
（1）对removeMatches进行条件判断，在launcher时不remove：
if (!(intent.getAction() != null
&& intent.getAction().equals(intent.ACTION_MAIN)
&& intent.getCategories() != null && intent.getCategories()
.contains(intent.CATEGORY_HOME))) {
Slog.d(TAG, “launcher”);
} else {
if (removeMatches) {
pir.removeFilter(pa);
if (DEBUG_PREFERRED) {
Slog.v(TAG, "Removing match " + pa.mPref.mComponent);
}
break;
}
}
（2）
if (always && !pa.mPref.sameSet(query, priority)) {
Slog.i(TAG, "Result set changed, dropping preferred activity for "
- intent + " type " + resolvedType);
if (DEBUG_PREFERRED) {
Slog.v(TAG, "Removing preferred activity since set changed "
- pa.mPref.mComponent);
}
pir.removeFilter(pa);
// Re-add the filter as a “last chosen” entry (!always)
PreferredActivity lastChosen = new PreferredActivity(pa,
pa.mPref.mMatch, null, pa.mPref.mComponent, false);
pir.addFilter(lastChosen);
mSettings.writePackageRestrictionsLPr(userId);
return null;
}
上面这段修改为下面的内容：
if (always && !pa.mPref.sameSet(query, priority)) {
if (!(intent.getAction() != null
&& intent.getAction().equals(intent.ACTION_MAIN)
&& intent.getCategories() != null && intent.getCategories()
.contains(intent.CATEGORY_HOME))) { // MTK ADD
Slog.i(TAG,
"Result set changed, dropping preferred activity for "
- intent + " type " + resolvedType);
