Android 打开指定程序

Android App 打开指定程序

Core code:

Intent launchIntent = getPackageManager().getLaunchIntentForPackage(appFullName);

Sample

    private void openTheSpecificApp (){
    	String appFullName = "your app full name";
        Intent launchIntent = getPackageManager().getLaunchIntentForPackage(appFullName);
        if (launchIntent != null) {
            startActivity(launchIntent);//null pointer check in case package name was not found
        }
    }

Notice: appFullName should be the FULL NAME of that APP, like com.android.settings …

核心代码：

Intent launchIntent = getPackageManager().getLaunchIntentForPackage(appFullName);

注意： appFullName 一定要是完整的app软件名字, 比如 com.android.settings。
