Android的错误了java.lang.RuntimeException [英] Android java.lang.RuntimeException error
问题描述
我试图建立我的团结Android插件。但是,当我这样做,我得到了如下的错误日志中的logcat:

我做了,为什么会这样搜索,并才知那是因为我的意图的问题。而且,我需要我的活动添加到我的清单文件。然而,这是我的清单文件:
<清单的xmlns:机器人=http://schemas.android.com/apk/res/android
包=com.example.marc
安卓版code =1
机器人:=的versionName1.0><用途-SDK
安卓的minSdkVersion =7

<类机器人:名字=android.intent.category.LAUNCHER/>
&所述; /意图滤光器> < /活性GT;
< /用途>
,从我所看到的,我的意图是那里的行<活动机器人:名字=com.example.marc.CompassActivity
,除非我的思想落后这是完全错误的?
只是为了补全的缘故,这里是我的java文件:

再次按我的想法,这就是我要传递给我的清单文件,例如,它被称为CompassActivity。显然,虽然我一定做错了什么事不然我也不会得到我的错误。可能有人请告诉我这是我在做什么错误/丢失?

我觉得
<活动机器人:名字=com.example.marc.CompassActivity
应
<活动机器人:名字=CompassActivity
(你已经在包属性提到的com.example.marc
机器人的值:名称应该是名存实亡活动类的。
由于您的清单文件说,主要活动类是com.example.marc.CompassActivity,运行环境寻找,但没有找到它作为你的主要活动类文件被命名为CompassAcitvity)
主要问题是,在运行时无法实例在MainActivity,因为它无法找到DexPathList类com.example.marc.CompassActivity
请参阅方法<一href=\"https://android.googlesource.com/platform/libcore-snapshot/+/ics-mr1/dalvik/src/main/java/dalvik/system/DexPathList.java\"相对=nofollow>的findClass()行310-323
如果成功找到了类,那么类对象返回其他明智的无效它返回到<一个href=\"https://android.googlesource.com/platform/libcore-snapshot/+/ics-mr1/dalvik/src/main/java/dalvik/system/BaseDexClassLoader.java\"相对=nofollow> BaseDexClassLoader(见第58行)与ClassNotFoundException的是空的情况下接收到这是在这种情况下发生的异常。
我觉得无论在构建过程中的主要活动课被排除或具有不同于清单提到的一些不同的名称。
I'm trying to build my Android plugin for Unity. But when I do, I get the follow error log in Logcat:

I did a search on to why this is happening and I discovered it is because of a problem with my intent. And that I needed to add my activity to my Manifest file. However, this is my manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.marc"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="7" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity android:name="com.example.marc.CompassActivity"
android:label="@string/app_name">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
And from what I can see, my intent is there in the line <activity android:name="com.example.marc.CompassActivity"
unless my thinking behind this is entirely wrong?
Just for completions sake, here is my java file:
package com.example.marc;
import com.unity3d.player.UnityPlayerActivity;
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.util.Config;
import android.util.Log;
import android.app.Activity;
public class CompassActivity extends UnityPlayerActivity
{
private static final String TAG = "Compass";
private SensorManager mSensorManager;
private Sensor mSensor;
static public float xmag;
static public float ymag;
static public float zmag;
private final SensorEventListener mListener = new SensorEventListener()
{
public void onSensorChanged(SensorEvent event)
{
if (Config.DEBUG) Log.d(TAG,
"sensorChanged (" + event.values[0] + ", " + event.values[1] + ", " + event.values[2] + ")");
xmag = event.values[0];
ymag = event.values[1];
zmag = event.values[2];
}
public void onAccuracyChanged(Sensor sensor, int accuracy)
{
}
};
@Override
protected void onCreate(Bundle icicle)
{
super.onCreate(icicle);
mSensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
}
@Override
protected void onResume()
{
if (Config.DEBUG) Log.d(TAG, "onResume");
super.onResume();
mSensorManager.registerListener(mListener, mSensor,
SensorManager.SENSOR_DELAY_GAME);
}
@Override
protected void onStop()
{
if (Config.DEBUG) Log.d(TAG, "onStop");
mSensorManager.unregisterListener(mListener);
super.onStop();
}
public static float getX()
{
return xmag;
}
public static float getY()
{
return ymag;
}
public static float getZ()
{
return zmag;
}
}
Again, as per my thinking, this is what I should be passing to my Manifest file, such, it is called "CompassActivity". Clearly though I must have done something wrong otherwise I wouldn't be getting the errors I am. Could someone please tell me what it is I am doing wrong / missing?

I think
<activity android:name="com.example.marc.CompassActivity"
SHOULD BE
<activity android:name="CompassActivity"
(you already mentioned "com.example.marc" in package attribute The value of android:name should be name of activity class only. Since your manifest file says main activity class is "com.example.marc.CompassActivity", runtime environment looks for it , but it doesn't find it as your main activity class file is named as "CompassAcitvity")
[EDIT]
Main issue is that the runtime is unable to Instantiate the MainActivity because it is not able to find the class "com.example.marc.CompassActivity" in DexPathList
See method "findClass()" line 310-323
If a class is successfully found then a class object is returned other wise null it is returned to BaseDexClassLoader(see line 58) And ClassNotFoundException is thrown in case null is received which is happening in this case.
I think either main activity class is excluded during build process or it has some different name unlike mentioned in manifest.
