android crosswalk goback

MainActivity.java

@Override

android remove title bar

android crosswalk new for file upload、camera test

1、build.gradle

repositories {
  maven {
    url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
  }
}

compile 'org.xwalk:xwalk_core_library:18.48.477.13'

2、active_main.xml

<org.xwalk.core.XWalkView android:id="@+id/activity_main"
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
</org.xwalk.core.XWalkView>

3、MainActivity.java

 




mXWalkView = (XWalkView) findViewById(R.id.activity_main);
mXWalkView.load("https://blueimp.github.io/jQuery-File-Upload/", null);


@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  mXWalkView.onActivityResult(requestCode, resultCode, data);
} 

 
4、AndroidManifest.xml

基本上 codova phonegap都是用webview裡面的addJavascriptInterfac 指定@JavascriptInterface 的java method，間接呼叫 回傳資料，達到和原生溝通


codova phone 等等都是包好，讓使用者方便使用，而且共同開發，讓呼叫 回傳 android 多版本能正常


ionic、titanic、react native 等等 為了在web app上速度更快或是對應呼叫 回傳時，開發速度更快

用CrossWalk包的話，可以肯定是最新的chrome，保證在操作上的正常！但app會非常的肥大~~

再不然就不能事先說明android 5以上才能存取 camera, file upload

Could not create an instance of Tooling API implementation using the specified Gradle installation gradle-2.10

If you try many way, can't finish.

1、reinstall android studio  ： remove all

2、delete all 

c:\user\your user name\.gradle

c:\user\your user name\.AndroidStudio2.0

3、reinstall android stuido 

be careful path and directory, C:\Program Files\Android   check this directory, have other Android Studio, likfe Android Studio1..... If have delete Android Studio1 directory, only keep Android Studio.

Looks like if I set the replication to "persistent" it resumes on app backgrounding

e.g._pull.persistent = YES;
