Question

我已打开现有的Firebase项目，但我在运行时收到错误。

                   Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.dji.GSDemo.GoogleMap. Make sure to call FirebaseApp.initializeApp(Context) first.

我尝试使用Firebase助手“连接到Firebase”，但获得了：

Could not parse the Android Application Module's Gradle config. Resolve gradle build issues and/or resync.

我尝试过更新SDK-Tools的内容：

但是这一切都像我的另一个火力棒项目一样有效。

我的问题是因为我已将Firebase活动添加到现有的非firebase项目。

这是我的构建gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
defaultConfig {

    ndk {
        abiFilters 'armeabi-v7a'
    }

    applicationId "com.dji.GSDemo.GoogleMap"
    minSdkVersion 23
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    //Enabling multidex support
    multiDexEnabled true //Mention in the doc

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

//Mention in the doc
dexOptions {
    incremental = true;
    preDexLibraries = false
    javaMaxHeapSize "4g" // 2g should be also OK
}

packagingOptions{
    doNotStrip "*/*/libdjivideo.so"

}
}
dependencies {

compile ('com.dji:dji-sdk:4.4.1')

我该如何解决？

请检查此问题的评论中的链接：

引起：java.lang.IllegalStateException：默认FirebaseApp未在此过程com.dji.GSDemo.GoogleMap中初始化。请务必先调用FirebaseApp.initializeApp（Context）。

对于第二个问题，请更新firebaseui：

改变这个：

<div id="dogmod" class="modal">

    <center>
        <form class="modal-content animate" style="margin: 0; padding-left:50px; padding-right:50px; padding-bottom:50px;">

            <div class="imgcontainer">
                <span onclick="document.getElementById('dogmod').style.display='none'" class="close" title="Close">&times;</span>
                <h1 align=center>Description</h1>

                <?php echo '<img src="data:image/jpeg;base64,'.base64_encode($_SESSION['petimg'] ).'" style="margin-top:50px;float:left; margin-right:50px;"/>'; ?>
                <h1 style="margin-top:50px;margin-bottom:50px">
                    <?php echo $_SESSION['petname'] ;?>
                </h1>
                <p style="margin-bottom:50px;">
                    <?php  echo $_SESSION['petdesc'] ;?>
                </p>
                <input type="button" value="Back" onclick=location.href='doga.php' class="button_1" style="  width: auto;padding: 10px 18px; background-color: #f44336; border:0px; color:white;">
                <h2> </h2>
        </form>
    </center>

    <script>
        // Get the modal
        var modal = document.getElementById('dogmod');

        // When the user clicks anywhere outside of the modal, close it
        window.onclick = function(event) {
            if (event.target == modal) {
                modal.style.display = "none";
            }
        }
    </script>


    </div>

到此：

implementation 'com.firebaseui:firebase-ui-database:2.3.0'

FirebaseUI compatibility

无法在现有Android Studio项目中连接到Firebase
