ap.O00000Oo(am.O0000ooo, an.this.O0000O0o.getText().toString())为true时满足条件. sources/android/support/v4/app/am.java

涉及到native的函数有如下：
$ grep -r native
resources/res/values-nb/strings.xml: <string name="abc_action_menu_overflow_description">Flere alternativer</string>
sources/android/support/v4/app/OO0OOOO0.java: public static native String getRho();

sources/android/support/v4/app/o000000o.java: public native void o000000o0();
sources/android/support/v4/app/OO0OOOO.java: public native byte[] OO0OOOO(byte[] bArr, byte[] bArr2);
盲猜o000000o0执行了加密函数，OO0OOOO执行了解密函数,因为解密需密钥，搜索得上下文：
