the uncompressed data in the APK file to be aligned on a 4-byte boundary (4 bytes is a well-performing value) so that the Android system can read the file using the Mmap () function (see the purpose of the function itself) to get higher performance on read resources ，Ps:1. Alignment on a 4-byte boundary means that, in general, the compiler bar 4 bytes are read as a unit, so that the CPU can access the variable efficiently and quickly (not before).2.

Through the introduction of the official article of the previous translation we have a preliminary impression of Sencha, and we have also generated the first sample application code framework through the wizard, so the next step may be that many people feel that you should look at the details of how an app is built, based on what the wizard suggests. But I think we can change the path of learning.Heaven Zhuhai The rudder is a relatively quick buck, so

1. Significance of SignatureTo ensure the legal ID of each application developer and prevent some open vendors from confusing and replacing installed programs by using the same package name, we need to make a unique signature for the APK file we released, ensure the consistency of the versions we release each time (for example, automatic update will not be unable to be installed because of version inconsistency ). 2. Signature stepsA. Create a keyB. U
