我一直在嘗試測試我的應用程序，在其中實現G +登錄並且在Android Studio的模擬器中運行應用程序時但表示我需要更新Google Play服務。當我想用真實設備測試我的應用程序時，應用程序無法啓動
我一直在努力做到這一點，所以我認爲我只是測試它在真實的設備上，但是當我做這個應用程序不啓動/運行。當我轉到設備上的設置和應用程序時，我可以看到該應用程序已安裝，但未顯示在應用程序抽屜或其他任何地方。
我得到我的運行選項卡下此異常左下角：
java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.madchallenge2016edwindaniel.upbirdwatchers/.LoginActivity } from null (pid=20620, uid=2000) not exported from uid 10154

這裏是我的清單：
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main"
android:theme="@style/AppTheme.NoActionBar" />
<intent-filter >
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<activity android:name=".RegisterActivity" />
<activity android:name=".LoginActivity" />
</application>
這裏我的啓動行爲的代碼ivity：
package com.madchallenge2016edwindaniel.upbirdwatchers;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class LoginActivity extends AppCompatActivity implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener{
private GoogleApiClient mGoogleApiClient;
private SignInButton mSignInButton;
private static final int RC_SIGN_IN = 9001;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
//Background
getWindow().setBackgroundDrawableResource(R.drawable.login_background);
// Configure sign-in to request the user's ID, email address, and basic
// profile. ID and basic profile are included in DEFAULT_SIGN_IN.
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
SignInButton mSignInButton = (SignInButton)findViewById(R.id.sign_in_button);
mSignInButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.sign_in_button:
signIn();
break;
// ...
}
}
});
}
//Start sign in
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
}
private void handleSignInResult(GoogleSignInResult result) {
if (result.isSuccess()) {
} else {
// Signed out, show unauthenticated UI.
// updateUI(false);
}
}
@Override
public void onConnected(Bundle bundle) {
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
public void setmSignInButton(SignInButton mSignInButton) {
this.mSignInButton = mSignInButton;
}
}
根據我得到的答案編輯我的清單文件後，我的應用程序現在運行。 這是我更新的清單文件看起來像：
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".LoginActivity"
android:exported="true">
<intent-filter >
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name=".RegisterActivity" />
<activity android:name=".MainActivity"
android:label="@string/title_activity_main"
android:theme="@style/AppTheme.NoActionBar"/>
</application>
