以下代码是发送Intent让系统打开文件的Activity源码：
importClass(java.io.File)
importClass (android.content.Intent)
importClass (android.net.Uri)
importClass (android.os.Build)
importClass (android.os.StrictMode)
function openAndroidFile( filepath){
var intent = new Intent();
try {
if (Build.VERSION.SDK_INT >= 25) {
//安卓7.0以上
var builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
var file = new File(filepath);
// intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//设置标记
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setAction(Intent.ACTION_VIEW);//动作，查看
intent.setDataAndType(Uri.fromFile(file), getMIMEType(filepath))
}else {
intent = new Intent("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// uri1 = Uri.parse(filepath );
// intent.setDataAndType(uri1, "text/plain");
//
uri2 = Uri.fromFile(new File(filepath ));
intent.setDataAndType(uri2, "text/plain");
}
}catch( az){
logd("openAndroidFile:"+az)
}
return intent
}
function getMIMEType(file) {
var MIME_MapTable=
//{后缀名， MIME类型}
