JNI在eclipse中出現Unresolved inclusion: 或Type 'jint' could not be resolved等解決方法

在eclipse中經常出現這類錯誤，include文件報錯或者是jint，jclass，JNIEnv could not be resolved等，但可以編譯通過，可以經過這個步驟消除這些錯誤或警告

1. 打開.project，刪除cdt部分

    <buildSpec>
        <buildCommand>
            <name>org.eclipse.cdt.managedbuilder.core.genmakebuilder</name>
            <triggers>clean,full,incremental,</triggers>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>com.android.ide.eclipse.adt.ResourceManagerBuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>com.android.ide.eclipse.adt.PreCompilerBuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>org.eclipse.jdt.core.javabuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>com.android.ide.eclipse.adt.ApkBuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder</name>
            <triggers>full,incremental,</triggers>
            <arguments>
            </arguments>
        </buildCommand>
    </buildSpec>
    <natures>
        <nature>com.android.ide.eclipse.adt.AndroidNature</nature>
        <nature>org.eclipse.jdt.core.javanature</nature>
        <nature>org.eclipse.cdt.core.cnature</nature>
        <nature>org.eclipse.cdt.core.ccnature</nature>
        <nature>org.eclipse.cdt.managedbuilder.core.managedBuildNature</nature>
        <nature>org.eclipse.cdt.managedbuilder.core.ScannerConfigNature</nature>
    </natures>

2. 刪除.cproject文件

3. 打開工程，refresh，然后右鍵->properties->Android Tools -> Add Native Support

經過上述步驟就不會出現之前的那些錯誤和警告了。
