在app中開啟外部app

筆記一下開外部app的寫法

private void startOthersApp(String packagename) {
Intent i = new Intent(Intent.ACTION_MAIN);
PackageManager manager = getPackageManager();
try {
i = manager.getLaunchIntentForPackage(packagename);

if (i == null)
throw new PackageManager.NameNotFoundException();
else {
i.addCategory(Intent.CATEGORY_LAUNCHER);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
} catch (PackageManager.NameNotFoundException e) {
}
}

android emulator "Unfortunately, launcher has stopped."

從API 18(Android 4.3)開始我的模擬器就呈現跑不動的狀態，跑些自己寫的簡單demo還可，反倒是點個應用程式清單去看所有App就掛了，連launcher都掛掉還以為是bug哩XD

其實是VM heap給不夠，可能Android 4.3之後heap吃重程度大吧？！
調大就好，如下圖
