使用Python 3和Cython 0.25-2使用Buildozer編譯Kivy

Question

我無法使用buildozer或p4a進行編譯。 我最接近的是使用buildozer。

• 我正在使用Kivy 1.10.1；
• Cython 0.25.2
• 嘗試使用android-ndk-16b和crystax-10.3.2。
• 嘗試過也將hostpython3置於要求中，但也不起作用。

我的buildozer.spec的一部分：

# (list) Application requirements
# comma seperated e.g. requirements = sqlite3,kivy
requirements = sqlite3,python3crystax,kivy,datetime,plyer,ecdsa,paramiko,pyjnius

# (int) Android API to use
android.api = 19

# (int) Minimum API required
android.minapi = 13

# (int) Android SDK version to use
android.sdk = 20

# (str) Android NDK version to use
android.ndk = 10.3.2

# (bool) Use --private data storage (True) or --dir public storage (False)
android.private_storage = False

# (str) Android NDK directory (if empty, it will be automatically downloaded.)
android.ndk_path = /home/awulll/python-for-android/crystax-ndk-10.3.2/

# (str) Android SDK directory (if empty, it will be automatically downloaded.)
android.sdk_path = /home/awulll/Android/Sdk/

我得到的錯誤：

有任何想法嗎？

我現在使用：“ android.private_storage = True”（之前為False），代碼已編譯，但現在在我的android上折痕了。

在編譯結束時，我收到以下消息：

第2版​​：

在我的logcat中，我發現了加密錯誤，但是當我將此作為要求時，我無法編譯。 logcat的：

嘗試使用加密作為要求時發現了新錯誤：

[INFO]:    No dist exists that meets your requirements, so one will be built.
[ERROR]:   Didn't find any valid dependency graphs.
[ERROR]:   This means that some of your requirements pull in conflicting dependencies.
[ERROR]:   Exiting.

Answer 1

在您的需求行中包含hostpython

# (list) Application requirements
# comma seperated e.g. requirements = sqlite3,kivy
requirements = hostpython3crystax
