最近要做一个打开第三方apk的功能,只给了一个apk,通过自己获取包名然后在实现;需求是如果第三方apk已经打开,则直接把界面显示出来,如果未打开,则启动。
首先获取bao包名,直接上代码;
/**
* 获取包名
*
* @return
*/
public static String getPackagenameKemobilevideo() {
String archiveFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MobileVideo.apk";//安装包路径
PackageManager pm = ContextHolder.getContext().getPackageManager();
PackageInfo info = pm.getPackageArchiveInfo(archiveFilePath, PackageManager.GET_ACTIVITIES);
if (info != null) {
ApplicationInfo appInfo = info.applicationInfo;
String appName = pm.getApplicationLabel(appInfo).toString();
String packageName = appInfo.packageName; //得到安装包名称
String version = info.versionName; //得到版本信息
LogUtil.e("MainActivity", "packageName:" + packageName + ";version:" + version);
return packageName;
}
return "";
}
获取到包名就可以启动了,通过度娘找到好几种办法,各有优缺点:
1、最简单的情况:只有包名
/**
* 启动第三方apk
* 直接打开 每次都会启动到启动界面,每次都会干掉之前的,从新启动
* XXXXX : 包名
*/
public static void launchAPK1() {
PackageManager packageManager = ContextHolder.getContext().getPackageManager();
Intent it = packageManager.getLaunchIntentForPackage("XXXXX");
ContextHolder.getContext().startActivity(it);
}
2、也是根据包名启动
/**
* 启动第三方apk
* 内嵌在当前apk内打开,每次启动都是新的apk,你会发现打开了两个apk
* XXXXX : 包名
*/
public static void launchAPK2() {
PackageInfo pi = null;
try {
pi = ContextHolder.getContext().getPackageManager().getPackageInfo("XXXX", 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
resolveIntent.setPackage(pi.packageName);
List<ResolveInfo> apps = ContextHolder.getContext().getPackageManager().queryIntentActivities(resolveIntent, 0);
ResolveInfo ri = apps.iterator().next();
if (ri != null) {
String packageName = ri.activityInfo.packageName;
String className = ri.activityInfo.name;
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
ComponentName cn = new ComponentName(packageName, className);
intent.setComponent(cn);
ContextHolder.getContext().startActivity(intent);
}
}
3、还是通过包名启动,这种方式正好满足我的需求
/**
* 启动第三方apk
*
* 如果已经启动apk,则直接将apk从后台调到前台运行(类似home键之后再点击apk图标启动),如果未启动apk,则重新启动
*/
public static void launchAPK3() {
Intent intent = getAppOpenIntentByPackageName(ContextHolder.getContext(), PACKAGENAME_KEMOBILEVIDEO);
ContextHolder.getContext().startActivity(intent);
}
public static Intent getAppOpenIntentByPackageName(Context context, String packageName) {
String mainAct = null;
PackageManager pkgMag = context.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_NEW_TASK);
@SuppressLint("WrongConstant") List<ResolveInfo> list = pkgMag.queryIntentActivities(intent,
PackageManager.GET_ACTIVITIES);
for (int i = 0; i < list.size(); i++) {
ResolveInfo info = list.get(i);
if (info.activityInfo.packageName.equals(packageName)) {
mainAct = info.activityInfo.name;
break;
}
}
if (TextUtils.isEmpty(mainAct)) {
return null;
}
intent.setComponent(new ComponentName(packageName, mainAct));
return intent;
}
上面三种都是通过包名启动,如果要启动到指定的界面
1、启动第三方指定页面。(这个方法有限制,第三方页面 Activity的属性Export=“true”)
启动页貌似是默认是true,其他页面默认是false
/**
* 启动第三方apk
* 直接打开 每次都会启动到启动界面
*/
public static void launchAPK4() {
Intent intent = new Intent(pk_name);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ComponentName comp = new ComponentName("com.android.settings", "com.android.settings.Settings");
intent.setComponent(comp);
ContextHolder.getContext().startActivity(intent);
}
2、隐式启动第三方应用
/**
* 启动第三方apk
* 直接打开 每次都会启动到启动界面
*/
public static void launchAPK5() {
Intent intent = new Intent();
intent.setAction(action);
intent.addCategory(category);
intent.setDataAndType("abc://www.baidu.com","image/gif");
ContextHolder.getContext().startActivity(intent);
}
条件1:IntentFilter 至少有一个action 至少有一个Category 可以没有Data和Type
条件2:如果有Data,参数中Data必须符合Data规则
条件3:Action和Category必须同时匹配Activity中的一个Action和一个Category(Category 默认:android.intent.category.DEFAULT)
