자신의 의도에서 다른 응용 프로그램 열기
내 프로그램을 업데이트하는 방법과 미리 정의 된 Uri (예 : SMS 또는 전자 메일)를 사용하여 프로그램을 여는 방법을 알고 있습니다.
MyTracks를 열 의도를 만들 수있는 방법이나 그들이 어떤 의도를 듣지 못하는 다른 응용 프로그램을 만들 수 있는지 알아야합니다.
DDMS 에서이 정보를 얻었지만이를 사용할 수있는 의도로 바꾸는 데 성공하지 못했습니다. MyTracks를 수동으로 열 때 가져옵니다.
당신의 도움을 주셔서 감사합니다

첫째, 안드로이드에서 "애플리케이션"의 개념은 약간 확장 된 것입니다.
응용 프로그램 (기술적으로 프로세스)에는 여러 활동, 서비스, 콘텐츠 공급자 및 / 또는 브로드 캐스트 리스너가있을 수 있습니다. 둘 중 하나 이상이 실행중인 경우 응용 프로그램이 시작되어 실행 중입니다 (프로세스).
따라서 식별해야 할 것은 "응용 프로그램을 시작하는 방법"입니다.
좋아 ... 여기 당신이 시도 할 수있는 것이 있습니다 :
- 과 의도를 생성
action=MAIN하고category=LAUNCHER - 를
PackageManager사용하여 현재 컨텍스트에서 가져 오기context.getPackageManager packageManager.queryIntentActivity(<intent>, 0)의도가 어디에category=LAUNCHER,action=MAIN또는packageManager.resolveActivity(<intent>, 0)주 / 실행으로 첫 활동을 얻기 위해ActivityInfo관심있는 사람을 얻으십시오- 로부터
ActivityInfo, 얻을packageName및name - 마지막으로,와 함께 또 다른 의도를 만들고
category=LAUNCHER,action=MAIN,componentName = new ComponentName(packageName, name)및setFlags(Intent.FLAG_ACTIVITY_NEW_TASK) - 드디어,
context.startActivity(newIntent)
나는 이렇게 일했다.
/** Open another app.
* @param context current Context, like Activity, App, or Service
* @param packageName the full package name of the app to open
* @return true if likely successful, false if unsuccessful
*/
public static boolean openApp(Context context, String packageName) {
PackageManager manager = context.getPackageManager();
try {
Intent i = manager.getLaunchIntentForPackage(packageName);
if (i == null) {
return false;
//throw new ActivityNotFoundException();
}
i.addCategory(Intent.CATEGORY_LAUNCHER);
context.startActivity(i);
return true;
} catch (ActivityNotFoundException e) {
return false;
}
}
사용법 예 :
openApp(this, "com.google.android.maps.mytracks");
그것이 누군가를 돕기를 바랍니다.
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(ComponentName.unflattenFromString("com.google.android.maps.mytracks/com.google.android.apps.mytracks.MyTracks"));
intent.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(intent);
편집하다 :
의견에서 제안한 것처럼 앞에 한 줄을 추가하십시오. startActivity(intent);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
활성화하려는 패키지 이름이 이미있는 경우 좀 더 일반적인 다음 코드를 사용할 수 있습니다.
PackageManager pm = context.getPackageManager();
Intent appStartIntent = pm.getLaunchIntentForPackage(appPackageName);
if (null != appStartIntent)
{
context.startActivity(appStartIntent);
}
MAIN 활동을 정기적으로 시작하는 방법으로 주요 활동을 찾지 못한 경우에 더 효과적이라는 것을 알았습니다.
이것은 MasterGaurav 솔루션을 기반으로 한 솔루션 코드입니다.
private void launchComponent(String packageName, String name){
Intent launch_intent = new Intent("android.intent.action.MAIN");
launch_intent.addCategory("android.intent.category.LAUNCHER");
launch_intent.setComponent(new ComponentName(packageName, name));
launch_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
activity.startActivity(launch_intent);
}
public void startApplication(String application_name){
try{
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
List<ResolveInfo> resolveinfo_list = activity.getPackageManager().queryIntentActivities(intent, 0);
for(ResolveInfo info:resolveinfo_list){
if(info.activityInfo.packageName.equalsIgnoreCase(application_name)){
launchComponent(info.activityInfo.packageName, info.activityInfo.name);
break;
}
}
}
catch (ActivityNotFoundException e) {
Toast.makeText(activity.getApplicationContext(), "There was a problem loading the application: "+application_name,Toast.LENGTH_SHORT).show();
}
}
반대로 솔루션을 사용하여 원하는 응용 프로그램이 현재 설치되어 있지 않을 때 호출되는 함수로 스 니펫을 확장했습니다. :이처럼 작동 그래서 패키지 이름으로 실행 응용 프로그램입니다. 찾을 수없는 경우 Android 마켓을 엽니 다 . 이 패키지에 대해 Google Play를 실행하십시오 .
public void startApplication(String packageName)
{
try
{
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(intent, 0);
for(ResolveInfo info : resolveInfoList)
if(info.activityInfo.packageName.equalsIgnoreCase(packageName))
{
launchComponent(info.activityInfo.packageName, info.activityInfo.name);
return;
}
// No match, so application is not installed
showInMarket(packageName);
}
catch (Exception e)
{
showInMarket(packageName);
}
}
private void launchComponent(String packageName, String name)
{
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.setComponent(new ComponentName(packageName, name));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
private void showInMarket(String packageName)
{
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageName));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
그리고 그것은 다음과 같이 사용됩니다 :
startApplication("org.teepee.bazant");
존재하는 경우 응용 프로그램을 열거 나 설치를 위해 Play 스토어 응용 프로그램을 엽니 다.
private void open() {
openApplication(getActivity(), "com.app.package.here");
}
public void openApplication(Context context, String packageN) {
Intent i = context.getPackageManager().getLaunchIntentForPackage(packageN);
if (i != null) {
i.addCategory(Intent.CATEGORY_LAUNCHER);
context.startActivity(i);
} else {
try {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageN)));
}
catch (android.content.ActivityNotFoundException anfe) {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + packageN)));
}
}
}
이것을 사용하십시오 :
PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.package.name");
startActivity(intent);
내 응용 프로그램 활동에서 다른 응용 프로그램 활동을 시작하려면 그것은 나를 위해 잘 작동합니다.
Below code will work if the another application already installed in your phone otherwise it is not possible to redirect form one app to another app.So make sure your app launched or not
Intent intent = new Intent();
intent.setClassName("com.xyz.myapplication", "com.xyz.myapplication.SplashScreenActivity");
startActivity(intent);
// This works on Android Lollipop 5.0.2
public static boolean launchApp(Context context, String packageName) {
final PackageManager manager = context.getPackageManager();
final Intent appLauncherIntent = new Intent(Intent.ACTION_MAIN);
appLauncherIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resolveInfos = manager.queryIntentActivities(appLauncherIntent, 0);
if ((null != resolveInfos) && (!resolveInfos.isEmpty())) {
for (ResolveInfo rInfo : resolveInfos) {
String className = rInfo.activityInfo.name.trim();
String targetPackageName = rInfo.activityInfo.packageName.trim();
Log.d("AppsLauncher", "Class Name = " + className + " Target Package Name = " + targetPackageName + " Package Name = " + packageName);
if (packageName.trim().equals(targetPackageName)) {
Intent intent = new Intent();
intent.setClassName(targetPackageName, className);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
Log.d("AppsLauncher", "Launching Package '" + packageName + "' with Activity '" + className + "'");
return true;
}
}
}
return false;
}
Since applications aren't allowed to change many of the phone settings, you can open a settings activity just like another application.
Look at you LogCat output after you actually modified the setting manually:
INFO/ActivityManager(1306): Starting activity: Intent { act=android.intent.action.MAIN cmp=com.android.settings/.DevelopmentSettings } from pid 1924
Then use this to display the settings page from your app:
String SettingsPage = "com.android.settings/.DevelopmentSettings";
try
{
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(ComponentName.unflattenFromString(SettingsPage));
intent.addCategory(Intent.CATEGORY_LAUNCHER );
startActivity(intent);
}
catch (ActivityNotFoundException e)
{
log it
}
For API level 3+, nothing more then one line of code:
Intent intent = context.getPackageManager().getLaunchIntentForPackage("name.of.package");
Return a CATEGORY_INFO launch Intent (apps with no launcher activity, wallpapers for example, often use this to provide some information about app) and, if no find it, returns the CATEGORY_LAUNCH of package, if exists.
If you're attempting to start a SERVICE rather than activity, this worked for me:
Intent intent = new Intent();
intent.setClassName("com.example.otherapplication", "com.example.otherapplication.ServiceName");
context.startService(intent);
If you use the intent.setComponent(...) method as mentioned in other answers, you may get an "Implicit intents with startService are not safe" warning.
Alternatively you can also open the intent from your app in the other app with:
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
where uri is the deeplink to the other app
Use following:
String packagename = "com.example.app";
startActivity(getPackageManager().getLaunchIntentForPackage(packagename));
Launch an application from another application on Android
Intent launchIntent = getActivity.getPackageManager().getLaunchIntentForPackage("com.ionicframework.uengage");
startActivity(launchIntent);
If you want to open another application and it is not installed you can send it to the Google App Store to download
First create the openOtherApp method for example
public static boolean openOtherApp(Context context, String packageName) { PackageManager manager = context.getPackageManager(); try { Intent intent = manager.getLaunchIntentForPackage(packageName); if (intent == null) { //the app is not installed try { intent = new Intent(Intent.ACTION_VIEW); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setData(Uri.parse("market://details?id=" + packageName)); context.startActivity(intent); } catch (ActivityNotFoundException e) { //throw new ActivityNotFoundException(); return false; } } intent.addCategory(Intent.CATEGORY_LAUNCHER); context.startActivity(intent); return true; } catch (ActivityNotFoundException e) { return false; } }
2.- Usage
openOtherApp(getApplicationContext(), "com.packageappname");
Try this code, Hope this will help you. If this package is available then this will open the app or else open the play store for downloads
String packageN = "aman4india.com.pincodedirectory";
Intent i = getPackageManager().getLaunchIntentForPackage(packageN);
if (i != null) {
i.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(i);
} else {
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageN)));
}
catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + packageN)));
}
}
You can use this command to find the package names installed on a device:
adb shell pm list packages -3 -f
Reference: http://www.aftvnews.com/how-to-determine-the-package-name-of-an-android-app/
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("package_name","package_name.class_name"));
intent.putExtra("grace", "Hi");
startActivity(intent);
