我正在尝试在我的Android设备上使用GCM发送通知,但我总是收到InvalidRegistration错误.

这是应该发送通知的PHP代码:

<?php
define('API_ACCESS_KEY', 'API KEY HIDDEN');

$registrationIds = array( $_GET['id']);

// prep the bundle
$msg = array
(
    'message'   => 'TestMessage',
    'title'     => 'TestTitle',
    'subtitle'  => 'TestSubtitle',
    'tickerText'    => 'TestTicker',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
);

$fields = array
(
    'registration_ids'  => $registrationIds,
    'data'          => $msg
);

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers …

我试图在libgdx中创建一个游戏,我想加载一个ttf字体并在屏幕上绘制一些文本但它在我的Android设备上不起作用,我明白了Unfortunately, game has stopped.我使用Android Studio作为IDE.它适用于桌面.

这是我加载字体的方式:

FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("font.ttf"));

我在logcat中收到以下错误:
