I'm stuck with these, tried possible solutions.

Answer 1

change build tool to

buildToolsVersion "21.0.1"

Answer 2

I faced the same kind of error. The reason was the .aidl file I was copying to client application which access the service was not under the proper package. Just try to create the package and make sure you copy the aidl file under proper package name of the app.

Answer 3

For me, this happen when I define overload methods with different signatures in aidl. Seem like overload methods is not supported.

Not allowed:

public void methodA(int a);
public void methodA(int a, String b);

Allowed:

public void methodA(int a);
public void methodB(int a, String b);

Found more is not allowed, cannot define String array in the signature Not Allowed:

public void methodA(String[] a);

Answer 4

I rename the aidl's package on Left navigation bar , and Consistent with the code in ***.aidl。

Answer 5

Try to build with --debug option and looking for "can be an out type, so you must declare it as in, out or inout."

Answer 6

I got the same mistake, but I fixed it. I guess you want to "Passing Objects over IPC", so do I.

My problem is that I missed the package define in the object aidl such as Rect.aidl, so please try to add package into your aidl file.

for example:

Rect.aidl

package android.graphics;  // important

// Declare Rect so AIDL can find it and knows that it implements
// the parcelable protocol.
parcelable Rect;
