Question

我似乎无法启动我的应用程序。它给我一个这样的错误：java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:522) at org.apache.spark.sql.hive.client.ClientWrapper.<init>(ClientWrapper.scala:204) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.apache.spark.sql.hive.client.IsolatedClientLoader.createClient(IsolatedClientLoader.scala:249) at org.apache.spark.sql.hive.HiveContext.metadataHive$lzycompute(HiveContext.scala:327) at org.apache.spark.sql.hive.HiveContext.metadataHive(HiveContext.scala:237) at org.apache.spark.sql.hive.HiveContext.setConf(HiveContext.scala:441) at org.apache.spark.sql.hive.HiveContext.defaultOverrides(HiveContext.scala:226) at org.apache.spark.sql.hive.HiveContext.<init>(HiveContext.scala:229) at org.apache.spark.sql.hive.HiveContext.<init>(HiveContext.scala:101) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:33) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:38) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:40) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:42)。我的清单有什么问题吗？

Error running second Activity: The activity must be exported or contain an intent-filter

Answer 1

看那里，＆＃34; android：exported =＆＃34; true＆＃34;＆gt;＆gt;＆＃34;，有两个＆＃34;＆gt;＆＃34;

Answer 2

在您的清单文件中更改此内容

<activity
    android:name="com.bill.myapplication1.MainActivity"
    android:label="@string/app_name"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Answer 3

<activity
        android:name="com.bill.myapplication1.MainActivity"
        android:label="@string/app_name"
        android:exported="true">>

你有双＆gt; near exported =＆＃34; true＆＃34;

Answer 4

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.bill.myapplication1.MainActivity"
        android:label="@string/app_name"
        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="com.bill.myapplication1.SecondActivity"
        android:label="@string/title_activity_second" >
    </activity>
</application>

＆＃34;运行第二个活动时出错：必须导出活动或包含一个intent-filter＆＃34;
