官网Instagram集成
一、创建WebView（登录对话框）
mWebView = new WebView(getContext());
mWebView.setVerticalScrollBarEnabled(false);
mWebView.setHorizontalScrollBarEnabled(false);
mWebView.setWebViewClient(new OAuthWebViewClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl(mUrl);
mWebView.setLayoutParams(FILL);
mContent.addView(mWebView);
二、WebView回调
private class OAuthWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d(TAG, "Redirecting URL " + url);
if (url.startsWith(InstagramApp.mCallbackUrl)) {
String urls[] = url.split("=");
mListener.onComplete(urls[1]);
InstagramDialog.this.dismiss();
return true;
}
return false;
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Log.d(TAG, "Page error: " + description);
super.onReceivedError(view, errorCode, description, failingUrl);
mListener.onError(description);
InstagramDialog.this.dismiss();
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
Log.d(TAG, "Loading URL: " + url);
super.onPageStarted(view, url, favicon);
mSpinner.show();
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
String title = mWebView.getTitle();
if (title != null && title.length() > 0) {
mTitle.setText(title);
}
Log.d(TAG, "onPageFinished URL: " + url);
mSpinner.dismiss();
}
}
三、接口监听
public interface OAuthDialogListener {
public abstract void onComplete(String accessToken);
public abstract void onError(String error);
}
四、创建对话框监听
InstagramDialog.OAuthDialogListener listener = new InstagramDialog.OAuthDialogListener() {
@Override
public void onComplete(String code) {
getAccessToken(code);
}
@Override
public void onError(String error) {
mListener.onFail("Authorization failed");
}
};
五、获取access_token
private void getAccessToken(final String code) {
mProgress.setMessage("Getting access token ...");
mProgress.show();
new Thread() {
@Override
public void run() {
Log.i(TAG, "Getting access token");
int what = WHAT_FETCH_INFO;
try {
URL url = new URL(TOKEN_URL);
// URL url = new URL(mTokenUrl + "&code=" + code);
Log.i(TAG, "Opening Token URL " + url.toString());
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
// urlConnection.connect();
OutputStreamWriter writer = new OutputStreamWriter(urlConnection.getOutputStream());
writer.write("client_id=" + mClientId + "&client_secret=" + mClientSecret
+ "&grant_type=authorization_code" + "&redirect_uri=" + mCallbackUrl + "&code=" + code);
writer.flush();
String response = streamToString(urlConnection.getInputStream());
Log.i(TAG, "response " + response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
mAccessToken = jsonObj.getString("access_token");
Log.i(TAG, "Got access token: " + mAccessToken);
String id = jsonObj.getJSONObject("user").getString("id");
String user = jsonObj.getJSONObject("user").getString("username");
String name = jsonObj.getJSONObject("user").getString("full_name");
mSession.storeAccessToken(mAccessToken, id, user, name);
Log.i(TAG, "userid： " + id);
} catch (Exception ex) {
what = WHAT_ERROR;
ex.printStackTrace();
}
mHandler.sendMessage(mHandler.obtainMessage(what, 1, 0));
}
}.start();
}
六、获取用户信息
private void fetchUserName() {
mProgress.setMessage("Finalizing ...");
new Thread() {
@Override
public void run() {
Log.i(TAG, "Fetching user info");
int what = WHAT_FINALIZE;
try {
URL url = new URL(API_URL + "/users/" + mSession.getId() + "/?access_token=" + mAccessToken);
Log.d(TAG, "Opening URL " + url.toString());
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = streamToString(urlConnection.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio = jsonObj.getJSONObject("data").getString("bio");
Log.i(TAG, "Got name: " + name + ", bio [" + bio + "]");
} catch (Exception ex) {
what = WHAT_ERROR;
ex.printStackTrace();
}
mHandler.sendMessage(mHandler.obtainMessage(what, 2, 0));
}
}.start();
}
七、调用显示登录页
public void authorize() {
// Intent webAuthIntent = new Intent(Intent.ACTION_VIEW);
// webAuthIntent.setData(Uri.parse(AUTH_URL));
// mCtx.startActivity(webAuthIntent);
mDialog.show();
}
八、App信息
public static final String CLIENT_ID = “379d744556c743c090c8a2014345435”;//更换
public static final String CLIENT_SECRET = "fd6ec75e44054545345088ad2d72f2253";
public static final String CALLBACK_URL = "instagram://connect";
分享、
File file = new File(videoPath);
Uri uri = Uri.fromFile(file);
Intent share = new Intent(Intent.ACTION_SEND);
// Set the MIME type
share.setType(type);
List
List
if (!resInfo.isEmpty()) {
for (ResolveInfo r : resInfo) {
Intent targeted = new Intent(Intent.ACTION_SEND);
targeted.setType(type);
ActivityInfo activityInfo = r.activityInfo;
if(activityInfo.packageName.contains("com.instagram.android")
|| activityInfo.name.contains("com.instagram.android.activity.ShareHandlerActivity")) {
targeted.putExtra(Intent.EXTRA_SUBJECT, "subject");
targeted.putExtra(Intent.EXTRA_TEXT, "your text");
targeted.putExtra(Intent.EXTRA_STREAM, uri);
// targeted.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
targeted.setPackage(activityInfo.packageName);
targetedShareIntents.add(targeted);
}
}
if (targetedShareIntents.size() == 0) {
L.showToast(getResources().getString(R.string.no_client) + ":instagram");
return;
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
if (chooserIntent == null) {
return;
}
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
try {
startActivity(chooserIntent);
} catch (android.content.ActivityNotFoundException ex) {
L.showToast(getResources().getString(R.string.no_client) + ":instagram");
}
