本文介绍了使用Facebook API无法获取位置和电子邮件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的Android应用程序中，我开发了此代码以登录我的帐户，并获取用户属性，如名称，位置和电子邮件。问题是我可以得到这个名字，但是我无法获得电子邮件和位置。当我尝试我的代码没有尝试抓住应用程序粉碎和我的日志点在 getproperty（电子邮件）和 getlocation（）。当我使用尝试。应用程序工作，但没有电子邮件或位置。

解决方案
问题是您没有要求权限：
authButton.setReadPermissions（Arrays.asList（user_likes，user_status 电子邮件， user_birthday））;
但是，您使用的是较旧的Facebook SDK，而。下面我将根据最新的API给你一个完整的Facebook登录示例代码。请记住，您必须先在 developers.facebook 中添加您的应用程序作为提到。
public class LoginActivity extends ActionBarActivity {
@Override
protected void onActivityResult（int requestCode，int responseCode，Intent data）
{
super.onActivityResult（requestCode，responseCode，data）;
callbackManager.onActivityResult（requestCode，responseCode，data）;
}
@Override
protected void onCreate（Bundle savedInstanceState）
{
super.onCreate（savedInstanceState）;
FacebookSdk.sdkInitialize（this.getApplicationContext（））;
setContentView（R.layout.activity_login）;
callbackManager = CallbackManager.Factory.create（）;
loginButton =（LoginButton）findViewById（R.id.loginFaceBook_button）;
列表< String> permissionNeeds = Arrays.asList（user_photos，email，user_birthday，public_profile）;
loginButton.setReadPermissions（permissionNeeds）;
loginButton.registerCallback（callbackManager，new FacebookCallback< LoginResult>（）
{
@Override
public void onSuccess（LoginResult loginResult）
{
System.out.println（onSuccess）;
GraphRequest request = GraphRequest.newMeRequest
（loginResult.getAccessToken（），new GraphRequest.GraphJSONObjectCallback（）
{
@覆盖
public void onCompleted（JSONObject对象，GraphResponse响应）
{
//应用程序代码
Log.v（LoginActivity，response.toString（））;
//System.out.println(\"Check：+ response.toString（））;
try
{
String id = object.getString（id）;
String name = object.getString（name）;
String email = object.getString（email）;
String gender = object.getString（gender）;
String birthday = object.getString（birthday）;
System.out.println（id +，+ name +，+ email +，+ gender +，+ birthday）;
}
catch（JSONException e）
{
e.printStackTrace（）;
}
}
}）;
Bundle parameters = new Bundle（）;
parameters.putString（fields，id，name，email，gender，birthday）;
request.setParameters（parameters）;
request.executeAsync（）;
}
@Override
public void onCancel（）
{
System.out.println（onCancel）;
}
@Override
public void onError（FacebookException exception）
{
System.out.println（onError）;
Log.v（LoginActivity，exception.getCause（）。toString（））;
}
}）;
}
}
如果要使用片段而不是 ActionBarActivity ，只需添加 loginButton.setFragment（this）; 您的许可行。
manifest.xml：
< uses -permission android：name =android.permission.INTERNET/>
< uses-permission android：name =android.permission.ACCESS_COARSE_LOCATION/>
< uses-permission android：name =android.permission.ACCESS_FINE_LOCATION/>
< application
<！ - 你的其他attrs ..-->
< meta-data
android：name =com.facebook.sdk.ApplicationId
android：value =@ string / app_id/> <！ - 从developers.facebook获取这个 - >
< activity
android：name =com.facebook.FacebookActivity
android：configChanges =keyboard | keyboardHidden | screenLayout | screenSize | orientation
android：theme = @android：style / Theme.Translucent.NoTitleBar
android：label =@ string / app_name/>
您还需要向应用程序添加哈希键。这是一个使用代码执行此操作的方法：
try
{
//粘贴您的包名称在第一个参数
PackageInfo info = getPackageManager（）。getPackageInfo（PUT_YOUR_PACKAGE_NAME_HERE，
PackageManager.GET_SIGNATURES）;
for（android.content.pm.Signature signature：info.signatures）
{
MessageDigest md = MessageDigest.getInstance（SHA）;
md.update（signature.toByteArray（））;
String sign = Base64.encodeToString（md.digest（），Base64.DEFAULT）;
Log.e（MY KEY HASH：，sign）;
Toast.makeText（getApplicationContext（），sign，Toast.LENGTH_LONG）.show（）;
}
}
catch（PackageManager.NameNotFoundException e）
{
}
catch（NoSuchAlgorithmException e）
{
}
将它打印出哈希键后，将其复制粘贴到
在grandle中，您应该添加 jcenter 在存储库中，并添加 compile'com.facebook.android:facebook-android-sdk:4.0.0' code code code code code code code code code code code code $ c $
jcenter（）
}
依赖关系{
classpath'com.android.tools.build:gradle:1.1.0'
//注意：不要放置应用依赖关系在这里;它们属于
//在单个模块中build.gradle文件
}
}
allprojects
{
repositories {
jcenter（）
/ *更多项目attrs .. * /
}
}
另一个grandle文件：
应用插件：'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion21.1.2
defaultConfig {
applicationIdYOUR_PACKAGE_NAME
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName1.0
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules .pro'
}
}
}依赖关系{
编译fileTree（dir：'libs'，include：['* .jar']）
compile'com .android.support：appcompat-v7：21.0.3'
compile'com.facebook.android:facebook-android-sdk:4.0.0'
}
编辑：
为了跟踪用户的位置，您将需要GPS跟踪器，像对象，我认为这不是你想要的。所以你的权限应该是 List< String> permissionNeeds = Arrays.asList（user_photos，email，user_birthday，public_profile）; 现在您应该可以检索用户的电子邮件
In my Android application I developed this code to login with my account and get user property like name, location and email. The problem is I can get the name, but I can't get the email and the location. When I tried my code without try catch the application crush and my log point in getproperty("email") and getlocation(). When I use the try. The application work but there is no email or location.

解决方案
The issue is that you have not asked for permissions:
authButton.setReadPermissions(Arrays.asList("user_likes", "user_status","email","user_birthday"));
However, you are using an older Facebook SDK, while the newest SDK is 4.0.+. Below, I will give you a full sample code for Facebook login, based on the newest API. Keep in mind that you first have to add your application in developers.facebook as the documentation mentions out.
public class LoginActivity extends ActionBarActivity{
@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data)
{
super.onActivityResult(requestCode, responseCode, data);
callbackManager.onActivityResult(requestCode, responseCode, data);
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(this.getApplicationContext());
setContentView(R.layout.activity_login);
callbackManager = CallbackManager.Factory.create();
loginButton = (LoginButton) findViewById(R.id.loginFaceBook_button);
List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
loginButton.setReadPermissions(permissionNeeds);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
{
@Override
public void onSuccess(LoginResult loginResult)
{
System.out.println("onSuccess");
GraphRequest request = GraphRequest.newMeRequest
(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback()
{
@Override
public void onCompleted(JSONObject object, GraphResponse response)
{
// Application code
Log.v("LoginActivity", response.toString());
//System.out.println("Check: " + response.toString());
try
{
String id = object.getString("id");
String name = object.getString("name");
String email = object.getString("email");
String gender = object.getString("gender");
String birthday = object.getString("birthday");
System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday);
}
catch (JSONException e)
{
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel()
{
System.out.println("onCancel");
}
@Override
public void onError(FacebookException exception)
{
System.out.println("onError");
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
}
If you want to use Fragment instead of ActionBarActivity, the just add loginButton.setFragment(this); right after your permission line.
manifest.xml:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
<!-- your other attrs..-->
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/app_id"/> <!-- Get this one from developers.facebook -->
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name"/>
You will need to add to your application a hash key too. Here is a way to do this with code:
try
{
//paste Your package name at the first parameter
PackageInfo info = getPackageManager().getPackageInfo("PUT_YOUR_PACKAGE_NAME_HERE",
PackageManager.GET_SIGNATURES);
for (android.content.pm.Signature signature : info.signatures)
{
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String sign = Base64.encodeToString(md.digest(), Base64.DEFAULT);
Log.e("MY KEY HASH:", sign);
Toast.makeText(getApplicationContext(),sign, Toast.LENGTH_LONG).show();
}
}
catch (PackageManager.NameNotFoundException e)
{
}
catch (NoSuchAlgorithmException e)
{
}
After it prints you out the hash key, you copy paste it to your facebook.developer account, where your project is located.
In grandle, you should add jcenter in repositories and also add compile 'com.facebook.android:facebook-android-sdk:4.0.0' in dependecies.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects
{
repositories {
jcenter()
/*more project attrs..*/
}
}
And the other grandle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "YOUR_PACKAGE_NAME"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}
Edit:
In order to track the user's location, you will need a GPS Tracker, something like this. "user_location" permission does not return a lon, lat, but a Page object, which I think is not what you want. So, your permissions should be List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile"); and now you should be able to retrieve user's email
