修改android Launcher

由于项目需求更改，在此做保留以后方便使用

在 frameworks/base/core/java/com/android/internal/app/ResolverActivity.java 中作修改

根据需要默认Launcher来设置默认

private void setDefaultLauncher(String defPackageName,String defClassName) {

if ((defPackageName != null && defPackageName.trim().length() > 1) && (defClassName != null && defClassName.trim().length() > 0)) {

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 list = new ArrayList();

list = getPackageManager().queryIntentActivities(intent, 0);

final int N = list.size();

ComponentName[] set = new ComponentName[N];

int bestMatch = 0;

for (int i=0; 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);

getPackageManager().addPreferredActivity(filter, bestMatch, set,preActivity);

}

在onCreate方法中添加调用

protected void onCreate(Bundle savedInstanceState) {

//++++++++++++

boolean firstBoot = (Settings.System.getInt(getApplication().getContentResolver(),

Settings.System.DEFAULT_HOME_SETTING_CHANGED, 0) == 0);

if(firstBoot){

String defPackageName = "com.panasonic.india.flexuihome";

String defClassName = "com.panasonic.india.flexuihome.Launcher";

setDefaultLauncher(defPackageName,defClassName);

android.util.Log.i("deflauncher : ","deflauncher : PackageName = "+

defPackageName+" ClassName = "+defClassName);

Intent defIntent = new Intent();

defIntent.setClassName(defPackageName, defClassName);

defIntent.setAction("android.intent.action.MAIN");

defIntent.addCategory("android.intent.category.HOME");

defIntent.addCategory("android.intent.category.DEFAULT");

startActivity(defIntent);

Settings.System.putInt(getApplication().getContentResolver(),

Settings.System.DEFAULT_HOME_SETTING_CHANGED,1);

this.finish();

}

//++++++++++++

// Use a specialized prompt when we're handling the 'Home' app startActivity()

final int titleResource;

final Intent intent = makeMyIntent();

final Set categories = intent.getCategories();

if (Intent.ACTION_MAIN.equals(intent.getAction())

&& categories != null

&& categories.size() == 1

&& categories.contains(Intent.CATEGORY_HOME)) {

titleResource = com.android.internal.R.string.whichHomeApplication;

} else {

titleResource = com.android.internal.R.string.whichApplication;

}

onCreate(savedInstanceState, intent, getResources().getText(titleResource),

null, null, true);

}

DEFAULT_HOME_SETTING_CHANGED的设置

/android/framworks/base/

在core/java/android/provider/Settings.java的public static final class System extends NameValueTable{}中添加

public static final String DEFAULT_HOME_SETTING_CHANGED = "default_home_setting_changed";

packages/SettingsProvider/res/values/defaults.xml中添加

packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

在private void loadSystemSettings(SQLiteDatabase db){}中添加中添加

loadIntegerSetting(stmt, Settings.System.DEFAULT_HOME_SETTING_CHANGED, R.integer.default_launcher_value);
