我在我的应用程序中收到致命信号 11 (SIGSEGV)。它发生在按下按钮（onClick被执行），获取 KeyChain 别名的私钥，然后垃圾收集器下一次运行时。
更多信息：
- 我只能在三星 Galaxy S3 上重现这个（安装了 Android 4.1.2）
- 没有 ANR-Dialog，应用程序刚刚关闭
- 调用 KeyChain.getPrivateKey 后下次启动 GC 时会出现该错误。
复制示例：
public class MainActivity extends Activity implements KeyChainAliasCallback {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onClick(View v) throws Exception {
KeyChain.choosePrivateKeyAlias(this, this, null, null, null, -1, null);
}
@Override
public void alias(String alias) {
try {
KeyChain.getPrivateKey(MainActivity.this, alias);
System.gc(); //Trigger it manually or we could just wait and do some stuff...
} catch (Exception e) {
e.printStackTrace(); //No exeption since its a native fatal error
}
}
}
