java使用intent例子,Java Intent.resolveActivityInfo方法代码示例

import android.content.Intent; //导入方法依赖的package包/类

private void startActivity(String action, Uri uri, String type, Map extras, boolean bExpectResult, int requestCode, CallbackContext callbackContext) {

// Credit: https://github.com/chrisekelley/cordova-webintent

Intent i = (uri != null ? new Intent(action, uri) : new Intent(action));

if (type != null && uri != null) {

i.setDataAndType(uri, type); //Fix the crash problem with android 2.3.6

} else {

if (type != null) {

i.setType(type);

}

if (uri != null)

{

i.setData(uri);

}

}

for (String key : extras.keySet()) {

String value = extras.get(key);

// If type is text html, the extra text must sent as HTML

if (key.equals(Intent.EXTRA_TEXT) && type.equals("text/html")) {

i.putExtra(key, Html.fromHtml(value));

} else if (key.equals(Intent.EXTRA_STREAM)) {

// allowes sharing of images as attachments.

// value in this case should be a URI of a file

final CordovaResourceApi resourceApi = webView.getResourceApi();

i.putExtra(key, resourceApi.remapUri(Uri.parse(value)));

} else if (key.equals(Intent.EXTRA_EMAIL)) {

// allows to add the email address of the receiver

i.putExtra(Intent.EXTRA_EMAIL, new String[] { value });

} else {

i.putExtra(key, value);

}

}

i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

if (i.resolveActivityInfo(this.cordova.getActivity().getPackageManager(), 0) != null)

{

if (bExpectResult)

{

cordova.setActivityResultCallback(this);

((CordovaActivity) this.cordova.getActivity()).startActivityForResult(i, requestCode);

}
