尝试在Cordova中启动Intent时出现ActivityNotFoundException [英] ActivityNotFoundException when attempting to launch Intent in Cordova

问题描述

如何在android清单中创建活动/意图以修复以下错误...

How do I create an activity/intent in the android manifest to fix the error below...

我正在使用 https://github.com/MaginSoft/MFileChooser ，我可以看到选择器和浏览器中的文件，但出现"android.content.ActivityNotFoundException"错误

I am using https://github.com/MaginSoft/MFileChooser and I can see the picker and the file in the browser but I get 'android.content.ActivityNotFoundException' error

W/No activity found to handle file chooser intent.:
android.content.ActivityNotFoundException: No Activity found to handle
Intent { act=android.intent.action.GET_CONTENT cat=
android.intent.category.OPENABLE] typ=.doc,.docx,.rdf,.txt,.pdf,.odt }

这是插件中的Java代码.

here is the java code from the plugin..

public void chooseFile(CallbackContext callbackContext) {

        // type and title should be configurable
        Context context=this.cordova.getActivity().getApplicationContext();
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setClass(context,FileChooserActivity.class);

        Intent chooser = Intent.createChooser(intent, "Select File");
        cordova.startActivityForResult(this, chooser, PICK_FILE_REQUEST);

        PluginResult pluginResult = new PluginResult(PluginResult.Status.NO_RESULT);
        pluginResult.setKeepCallback(true);
        callback = callbackContext;
        callbackContext.sendPluginResult(pluginResult);
}

推荐答案

该错误告诉您该设备未安装能够处理该特定隐式意图的应用程序.尝试像这样启动意图之前，您需要检查应用程序是否可用:

The error is telling you that the device has no applications installed that are able to handle that particular implicit intent. You need to check whether an application is available before attempting to launch the intent like this:

// Verify that there are applications registered to handle this intent
// resolveActivity returns null if none are registered
if (intent.resolveActivity(getPackageManager()) != null) {
    startActivity(intent);
}
