I am trying to implement the Google Drive Stephen Wylie example ( here ). Here is my code:
package com.googledrive.googledriveapp; // For Google Drive / Play Services // Version 1.1 - Added new comments & removed dead code // Stephen Wylie - 10/20/2012 import java.io.IOException; import java.util.ArrayList; import android.accounts.Account; import android.accounts.AccountManager; import android.app.Activity; import android.app.ProgressDialog; import android.content.Context; import android.content.DialogInterface; import android.content.DialogInterface.OnClickListener; import android.content.Intent; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; import com.google.android.gms.auth.GoogleAuthException; import com.google.android.gms.auth.GoogleAuthUtil; import com.google.android.gms.auth.UserRecoverableAuthException; import com.google.android.gms.common.AccountPicker; import com.google.api.client.auth.oauth2.BearerToken; import com.google.api.client.auth.oauth2.Credential; import com.google.api.client.extensions.android2.AndroidHttp; import com.google.api.client.googleapis.extensions.android2.auth.GoogleAccountManager; import com.google.api.client.http.HttpRequestFactory; import com.google.api.client.http.HttpTransport; import com.google.api.client.http.json.JsonHttpRequest; import com.google.api.client.http.json.JsonHttpRequestInitializer; import com.google.api.client.json.jackson.JacksonFactory; import com.google.api.services.drive.Drive; import com.google.api.services.drive.Drive.Apps.List; import com.google.api.services.drive.Drive.Files; import com.google.api.services.drive.DriveRequest; import com.google.api.services.drive.DriveScopes; import com.google.api.services.drive.model.File; import com.google.api.services.drive.model.FileList; public class MainActivity extends Activity { private static final int CHOOSE_ACCOUNT=0; private static String accountName; private static int REQUEST_TOKEN=0; private Button btn_drive; private Context ctx = this; private Activity a = this; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // set up the GUI layout setContentView(R.layout.activity_main); // set the variables to access the GUI controls btn_drive = (Button) findViewById(R.id.btn_drive); btn_drive.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { chooseAccount(); } }); } public void chooseAccount() { Intent intent = AccountPicker.newChooseAccountIntent(null, null, new String[]{"com.google"}, false, null, null, null, null); startActivityForResult(intent, CHOOSE_ACCOUNT); } // Fetch the access token asynchronously. void getAndUseAuthTokenInAsyncTask(Account account) { AsyncTask<Account, String, String> task = new AsyncTask<Account, String, String>() { ProgressDialog progressDlg; AsyncTask<Account, String, String> me = this; @Override protected void onPreExecute() { progressDlg = new ProgressDialog(ctx, ProgressDialog.STYLE_SPINNER); progressDlg.setMax(100); progressDlg.setTitle("Validating..."); progressDlg.setMessage("Verifying the login data you entered...\n\nThis action will time out after 10 seconds."); progressDlg.setCancelable(false); progressDlg.setIndeterminate(false); progressDlg.setOnCancelListener(new android.content.DialogInterface.OnCancelListener() { public void onCancel(DialogInterface d) { progressDlg.dismiss(); me.cancel(true); } }); progressDlg.show(); } @Override protected String doInBackground(Account... params) { return getAccessToken(params[0]); } @Override protected void onPostExecute(String s) { if (s == null) { // Wait for the extra intent } else { accountName = s; getDriveFiles(); } progressDlg.dismiss(); } }; task.execute(account); } /** * Fetches the token from a particular Google account chosen by the user. DO NOT RUN THIS DIRECTLY. It must be run asynchronously inside an AsyncTask. * @param activity * @param account * @return */ private String getAccessToken(Account account) { try { return GoogleAuthUtil.getToken(ctx, account.name, "oauth2:" + DriveScopes.DRIVE_READONLY); // IMPORTANT: DriveScopes must be changed depending on what level of access you want } catch (UserRecoverableAuthException e) { // Start the Approval Screen intent, if not run from an Activity, add the Intent.FLAG_ACTIVITY_NEW_TASK flag. a.startActivityForResult(e.getIntent(), REQUEST_TOKEN); e.printStackTrace(); return null; } catch (GoogleAuthException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } private Drive getDriveService() { HttpTransport ht = AndroidHttp.newCompatibleTransport(); // Makes a transport compatible with both Android 2.2- and 2.3+ JacksonFactory jf = new JacksonFactory(); // You need a JSON parser to help you out with the API response Credential credential = new Credential(BearerToken.authorizationHeaderAccessMethod()).setAccessToken(accountName); HttpRequestFactory rf = ht.createRequestFactory(credential); Drive.Builder b = new Drive.Builder(ht, jf, null); b.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() { @Override public void initialize(JsonHttpRequest request) throws IOException { DriveRequest driveRequest = (DriveRequest) request; driveRequest.setPrettyPrint(true); driveRequest.setOauthToken(accountName); } }); return b.build(); } /** * Obtains a list of all files on the signed-in user Google Drive account. */ private void getDriveFiles() { Drive service = getDriveService(); Log.d("SiteTrack", "FUNCTION getDriveFiles()"); Files.List request; try { request = service.files().list(); // .setQ("mimeType=\"text/plain\""); } catch (IOException e) { e.printStackTrace(); return; } do { FileList files; try { Log.d("SiteTrack", request.toString()); files = request.execute(); } catch (IOException e) { e.printStackTrace(); Log.d("SiteTrack", "Exception"); return; } ArrayList<File> fileList = (ArrayList<File>) files.getItems(); Log.d("SiteTrack", "Files found: " + files.getItems().size()); for (File f : fileList) { String fileId = f.getId(); String title = f.getTitle(); Log.d("SiteTrack", "File " + fileId + ": " + title); } request.setPageToken(files.getNextPageToken()); } while (request.getPageToken() != null && request.getPageToken().length() >= 0); } protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) { if (requestCode == CHOOSE_ACCOUNT && resultCode == RESULT_OK) { accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME); GoogleAccountManager gam = new GoogleAccountManager(this); getAndUseAuthTokenInAsyncTask(gam.getAccountByName(accountName)); Log.d("SiteTrack", "CHOOSE_ACCOUNT"); } else if (requestCode == REQUEST_TOKEN && resultCode == RESULT_OK) { accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME); Log.d("SiteTrack", "REQUEST_TOKEN"); } } }
Here is my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.googledrive.googledriveapp" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <meta-data android:name="android.support.PARENT_ACTIVITY" android:value="android.app.ActivityGroup" /> </activity> </application> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.INTERNET" /> </manifest>
Here is my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/btn_drive" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Connect to Google Drive" /> </LinearLayout>
And here is the LogCat error that I get. This happens when the button is pressed:
10-28 00:25:28.637: E/AndroidRuntime(842): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.google.android.gms.common.account.CHOOSE_ACCOUNT (has extras) } 10-28 00:25:28.637: E/AndroidRuntime(842): at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1512) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.app.Instrumentation.execStartActivity(Instrumentation.java:1384) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.app.Activity.startActivityForResult(Activity.java:3190) 10-28 00:25:28.637: E/AndroidRuntime(842): at com.googledrive.googledriveapp.MainActivity.chooseAccount(MainActivity.java:67) 10-28 00:25:28.637: E/AndroidRuntime(842): at com.googledrive.googledriveapp.MainActivity$1.onClick(MainActivity.java:60) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.view.View.performClick(View.java:3511) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.view.View$PerformClick.run(View.java:14105) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.os.Handler.handleCallback(Handler.java:605) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.os.Handler.dispatchMessage(Handler.java:92) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.os.Looper.loop(Looper.java:137) 10-28 00:25:28.637: E/AndroidRuntime(842): at android.app.ActivityThread.main(ActivityThread.java:4424) 10-28 00:25:28.637: E/AndroidRuntime(842): at java.lang.reflect.Method.invokeNative(Native Method) 10-28 00:25:28.637: E/AndroidRuntime(842): at java.lang.reflect.Method.invoke(Method.java:511) 10-28 00:25:28.637: E/AndroidRuntime(842): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 10-28 00:25:28.637: E/AndroidRuntime(842): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 10-28 00:25:28.637: E/AndroidRuntime(842): at dalvik.system.NativeStart.main(Native Method)
Can anyone help?
