Answer 1

com.parse.mech.ParseApplication

将此类添加到清单中。

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.parse.mech.ParseApplication" on path:    /data/app/com.parse.mech-2.apk
09-27 17:44:48.422: E/AndroidRuntime(947):  at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:65)

将此添加到您的清单：

    <activity
        android:name=".ParseApplication"
        android:label="@string/app_name" >
    </activity>

Answer 2

当我从Eclipse运行应用程序直接将应用程序加载到我的手机时，我得到此错误，而在我的手机中，应用程序已在运行。所以，如果它对你来说一样，那么这不是问题。如果要避免该错误，可以尝试从手机/模拟器手动卸载应用程序，然后再次尝试从Eclipse运行该项目。希望它有所帮助。

Answer 3

：如果你的android名称前面有一个句点，你的android清单活动块中的路径：/data/app/com.parse.mech-2.apk上找不到类“com.parse.mech.ParseApplication”将附加包路径，因此如果您有“.com.parse.mech2”，它将查找“com.parse.com.parse.mech2”，因此要么删除句号，要么不提供全名。也像Simon说的那样你可能有编译时错误，链接时错误，运行时错误等.logcat有帮助，学习运行调试器也有帮助。

Answer 4

我认为您忘记在申请的班级名称之前添加.

喜欢name=.Mech

或者您可以添加完整路径

name = com.parse.mech.Mech

和thi也是

com.parse.mech.ParseStarterProjectActivity

你的清单应该是这样的

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.parse.mech"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="4"
    android:targetSdkVersion="15" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />

<application
    android:name="com.parse.mech.Mech"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name="com.parse.mech.ParseStarterProjectActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    <service android:name="com.parse.PushService" />

    <receiver android:name="com.parse.ParseBroadcastReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
    </receiver>
</application>
