Create and Implement interface
public interface IFbCallback<G, R> {
public void onFbRequestComplete(G graphUser, R response);
}
Add build.gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc3"
defaultConfig {
applicationId "com.dvmfashion"
minSdkVersion 15

I can see you are generating wrong hash key for Facebook. You must use your package name which is "com.al.name" instead of Facebook "com.facebook.samples.loginhowto".
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.al.name",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}

It is working.
LoginActivity:
public static CallbackManager callbackmanager;
Button fb_login;
private boolean fb_signincllicked = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_login);
//write this method in facebook button onclick:
}
public void onFblogin(boolean fb_btn) {
fb_signincllicked = fb_btn;
callbackmanager = CallbackManager.Factory.create();
// Set permissions
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "email"));
LoginManager.getInstance().registerCallback(callbackmanager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
final Set<String> deniedPermissions = loginResult.getRecentlyDeniedPermissions();
GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject json, GraphResponse response) {
if (response.getError() != null) {
// handle error
} else {
try {
if (deniedPermissions.contains("email")) {
LoginManager.getInstance().logInWithReadPermissions(Login_Activity.this, Arrays.asList("email"));
}
JSONObject jsonObject = new JSONObject();
jsonObject.put("full_name", json.getString("name"));
Toast.makeText(getApplicationContext(),json.get("id").toString() +json.getString("name"), Toast.LENGTH_LONG).show();
jsonObject.put("device_id", Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID));
jsonObject.put("fb_id", json.getString("id"));
jsonObject.put("signuptype", "1");
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}).executeAsync();
}
@Override
public void onCancel() {
Log.d("Cancel", "On cancel");
}
@Override
public void onError(FacebookException error) {
Log.d("Error", error.toString());
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (fb_signincllicked) {
callbackmanager.onActivityResult(requestCode, resultCode, data);
}
}
Add Dependence:
dependencies {
compile 'com.facebook.android:facebook-android-sdk:4.5.0'
}
strings.xml:
add your fb id in your strings file. Don't add directly in your manifest file. It gives you error.
<string name="fb_appid">xxxxxxxx</string>
Manifest_fie:
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/fb_appid" />
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="@string/app_name"
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
To Get Hash-Key:
try {
PackageInfo info = getPackageManager().getPackageInfo(
"your package name",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (PackageManager.NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
add your package name above.
run this code in debug mode then you will get developement key hash in log and run this code in release mode you will get release hashkey.Add both these keys, package name and class name in developer site.
