（備忘）Android app中呼叫啟動其他應用（系統應用和第三方應用）
阿新 • • 發佈：2019-02-18
一、開啟第三方應用
方法一
Intent intent=new Intent(); //包名 包名+類名（全路徑） intent.setClassName("com.linxcool", "com.linxcool.PlaneActivity"); startActivity(intent);
方法二
Intent intent = new Intent(); ComponentName comp = new ComponentName("com.linxcool","com.linxcool.PlaneActivity"); intent.setComponent(comp); intent.setAction("android.intent.action.MAIN"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);
方法三
出自storm的部落格。
這段程式碼會檢測app是否安裝，沒安裝的話會指向商店下載。
public static final String APP_PACKAGE_NAME = "com.*.*";//包名 /** * 啟動薄荷App* @param context */ public static void launchapp(Context context) { // 判斷是否安裝過App，否則去市場下載 if (isAppInstalled(context, APP_PACKAGE_NAME)) { context.startActivity(context.getPackageManager().getLaunchIntentForPackage(APP_PACKAGE_NAME)); } else { goToMarket(context, APP_PACKAGE_NAME); } } /** * 檢測某個應用是否安裝 * * @param context * @param packageName * @return */ public static boolean isAppInstalled(Context context, String packageName) { try { context.getPackageManager().getPackageInfo(packageName, 0); return true; } catch (NameNotFoundException e) { return false; } } /** * 去市場下載頁面 */ public static void goToMarket(Context context, String packageName) { Uri uri = Uri.parse("market://details?id=" + packageName); Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); try { context.startActivity(goToMarket); } catch (ActivityNotFoundException e) { } }
呼叫第三方應用的關鍵在於獲得第三方應用的包名和入口Activity類名。
獲得獲得第三方應用的包名和入口Activity類名
-
使用aapt
//aapt是sdk自帶的一個工具，在sdk\builds-tools\目錄下
1.以ES檔案瀏覽器為例，命令列中切換到aapt.exe目錄執行：aapt dump badging E:\apk\es3.apk
2.執行後的結果中以下兩行分別是應用包名package和入口activity名稱
package: name=’com.estrongs.Android.pop’//在輸出比較靠前的位置
launchable-activity: name=’com.estrongs.android.pop.view.FileExplorerActivity’
注：在android sdk目錄搜尋可以找到aapt.exe，如果沒有可以下載apktool。 -
檢視AndroidManifest.xml
1.使用apktool反編譯app：apktool.bat d es3.apk E:\apk\es
2.開啟AndroidManifest.xml
manifest節點的package屬性值是應用的包名：
查詢android.intent.action.MAIN和android.intent.category.LAUNCHER對應的activity，該activity對應的android:name屬性既是入口activity名稱，如下：
<activity android:theme=”@android:tyle/Theme.NoTitleBar” android:label=”@string/app_name” android:name=”com.estrongs.android.pop.view.FileExplorerActivity”> <intent-filter> <action android:name=”android.intent.action.MAIN” /> <category android:name=”android.intent.category.LAUNCHER” /> </intent-filter> </activity>
android.intent.action.MAIN決定應用程式最先啟動的Activity，android.intent.category.LAUNCHER決定應用程式是否顯示在
程式列表裡。
順便分享幾個應用的包名和入口Activity(用aapt獲得的)：
| app | package | launcher |
|---|---|---|
| 微博 | com.sina.weibo | com.sina.weibo.SplashActivity |
| 知乎 | com.zhihu.android | com.zhihu.android.ui.activity.GuideActivity |
| 薄荷 | com.app.one | com.app.one.ui.SplashActivity |
二、系統應用
1.從google搜尋內容
Intent intent = new Intent(); intent.setAction(Intent.ACTION_WEB_SEARCH); intent.putExtra(SearchManager.QUERY,"搜尋內容") startActivity(intent);
2.瀏覽網頁
Uri uri =Uri.parse("http://www.google.com"); Intent it = new Intent(Intent.ACTION_VIEW,uri); startActivity(it);
3.顯示地圖
Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = newIntent(Intent.Action_VIEW,uri); startActivity(it);
4.路徑規劃
Uri uri =Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); Intent it = newIntent(Intent.ACTION_VIEW,URI); startActivity(it);
5.撥打電話
Uri uri =Uri.parse("tel:xxxxxx"); Intent it = new Intent(Intent.ACTION_DIAL,uri); startActivity(it);
6.發簡訊
//方法1： Intent it = newIntent(Intent.ACTION_VIEW); it.putExtra("sms_body", "TheSMS text"); it.setType("vnd.android-dir/mms-sms"); startActivity(it); //方法2： Uri uri =Uri.parse("smsto:0800000123"); Intent it = newIntent(Intent.ACTION_SENDTO, uri); it.putExtra("sms_body", "TheSMS text"); startActivity(it); //方法三： String body="this is sms demo"; Intent mmsintent = newIntent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", number, null)); mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY,body); mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE,true); mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT,true); startActivity(mmsintent);
7.傳送彩信
Uri uri =Uri.parse("content://media/external/images/media/23"); Intent it = newIntent(Intent.ACTION_SEND); it.putExtra("sms_body","some text"); it.putExtra(Intent.EXTRA_STREAM, uri); it.setType("image/png"); startActivity(it); StringBuilder sb = new StringBuilder(); sb.append("file://"); sb.append(fd.getAbsoluteFile()); Intent intent = newIntent(Intent.ACTION_SENDTO, Uri.fromParts("mmsto", number, null)); // Below extra datas are all optional. intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_SUBJECT,subject); intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY,body); intent.putExtra(Messaging.KEY_ACTION_SENDTO_CONTENT_URI,sb.toString()); intent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE,composeMode); intent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT,exitOnSent); startActivity(intent);
8.傳送Email
Uri uri =Uri.parse("mailto:[email protected]"); Intent it = newIntent(Intent.ACTION_SENDTO, uri); startActivity(it); Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_EMAIL,"[email protected]"); it.putExtra(Intent.EXTRA_TEXT, "Theemail body text"); it.setType("text/plain"); startActivity(Intent.createChooser(it,"Choose Email Client")); Intent it=new Intent(Intent.ACTION_SEND); String[] tos={"[email protected]"}; String[]ccs={"[email protected]"}; it.putExtra(Intent.EXTRA_EMAIL, tos); it.putExtra(Intent.EXTRA_CC, ccs); it.putExtra(Intent.EXTRA_TEXT, "Theemail body text"); it.putExtra(Intent.EXTRA_SUBJECT, "Theemail subject text"); it.setType("message/rfc822"); startActivity(Intent.createChooser(it,"Choose Email Client")); Intent it = newIntent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_SUBJECT, "Theemail subject text"); it.putExtra(Intent.EXTRA_STREAM,"file:///sdcard/mysong.mp3"); sendIntent.setType("audio/mp3"); startActivity(Intent.createChooser(it,"Choose Email Client"));

10.解除安裝 apk
Uri uri =Uri.fromParts("package", strPackageName, null); Intent it = newIntent(Intent.ACTION_DELETE, uri); startActivity(it);
11.安裝 apk
Uri installUri = Uri.fromParts("package","xxx", null); returnIt = newIntent(Intent.ACTION_PACKAGE_ADDED, installUri); Intent intent = new Intent(Intent.ACTION_VIEW
