一、打开第三方应用
(1)
Intent intent=new Intent();
//包名 包名+类名(全路径)
intent.setClassName("com.jack", "com.jack.PlaneActivity");
startActivity(intent);
(2)
Intent intent = new Intent();
ComponentName comp = new ComponentName("com.jack","com.jack.PlaneActivity");
intent.setComponent(comp);
intent.setAction("android.intent.action.MAIN");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
(3)转载自https://blog.csdn.net/aaa111/article/details/41833189
public static final String APP_PACKAGE_NAME = "com.*.*";//包名
/**
* 启动薄荷App
* @param context
*/
public static void launchapp(Context context) {
// 判断是否安装过App,否则去市场下载
if (isAppInstalled(context, APP_PACKAGE_NAME)) {
context.startActivity(context.getPackageManager().getLaunchIntentForPackage(APP_PACKAGE_NAME));
} else {
goToMarket(context, APP_PACKAGE_NAME);
}
}
/**
* 检测某个应用是否安装
*
* @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;
}
}
/**
* 去市场下载页面
*/
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) {
}
}
